On the tiles at Russell Square tube station

In yesterday's post I mentioned that I have spotted maker's marks on tiled walls. For instance, above street level, Doulton of Lambeth employed various impressions as per this collection I pulled together almost 12 years ago (I have since found many more) but, until last week I had never seen anything similar on the Underground network.

I use Russell Square station quite often. It is a Lesley Green design, one of many that opened c1906 with ox-blood exteriors and beautifully-tiled and colour-coded connecting tunnels and platforms. I suspect it's because I get distracted by the gorgeous colours and the lovely hand-painted letters that I hadn't noticed this maker's mark:


The image on the left shows the exit tunnel from the westbound platform, but viewed as if coming from the lift. As you can see, there is an impression within a single tile on the left hand side. Here's a close-up:


G. Woolliscroft & Co was a floor tile maker, but there doesn't appear to be any remains of the Melville Road premises where these tiles would have been made. I wonder if Woolliscroft produced the tiles that line all other stations along the Piccadilly Line. If so, it was a huge commission! Seems more likely that quite a few companies in the Staffordshire Potteries area would have been working together on this project, with some companies making the tiles and others adding the colours, doing the glazing and firing. 

Hold the front page!!!! - Dougrose has written this piece about the tile makers although, annoyingly he doesn't identify where any marks tiles can be found, so I will henceforth be keeping my eyes peeled for more evidence – let me know if you see any.

The subterranean passage below Albertopolis

Heading to The Royal College of Music last week, it was a bit wet and windy* above ground so I made use of the pedestrian tunnel that links South Kensington station to approx mid-way up Exhibition Road. 

The tunnel is accessed directly from the station's ticket hall. At the station end there is there's a sharp right turn. On previous occasions I have been busy dodging groups of tourists and noisy schoolkids, but this time I happened to notice a brass marker set within the floor ahead of me:

Hmmm... interesting... I hadn't seen this name before. However, I have spotted a couple of Aberdeen Adamant signs in my travels such as the one below (where was this?!) – there also a similar one in Crouch end near the YMCA). 

I've paired it here with a pic from Borough High Street in Southwark, where embedded brass letters are gradually disappearing.

Back to the tunnel... I tried a quick online search for Roadamant but so far have found nothing. The address, 65 London Wall, is at the time of writing shrouded in scaffolding and plastic. Fingers crossed that the gorgeous substantial Art Nouveau railings that surround this huge building will be retained after renovations are complete. When/if I find out more information about the company I will add it here.

Along the same dog-leg section of the passage, just a few metres ahead, there is another company name embedded into the floor, bearing the name of Wilkes & Co.


Again, as per Roadamant and Nettlefolds from my last post, this is also name I have never noticed before. Devonshire Square is adjacent to Petticoat Lane market and today the site is mostly high rise glass-covered buildings.

Turning left into the main long stretch of the tunnel, the same Wilkes & Co markers are repeated at intervals. Then, at the entrance to The Natural History Museum gardens, another version is included which shows more information:


I've discovered that Wilke's Metal Flooring Co Ld (not Ltd., how nice!) seemed to work in conjunction with, or be one and the same as The Eureka Flooring Company, being as both companies were based in Devonshire Square and are shown a contractors for the grooved and channelled flooring installed at ground level within stable buildings that were at 63 Clerkenwell Road shown here in 2008 but demolished and replaced a few years later. Again, more information about this company needed. 

The quality of the tiles along the tunnel is impressive. I kept my eye out for maker's marks on them but, although I am pretty sure there must be at least one bit of evidence along there, I didn't manage to spot anything that day. Mind you, I only started looking from half way and I suspect any marks might be at the station end. I will check next time I am there.


Something I did notice, however, was the strange indentations within the skirtings. These are approx 40 paces apart, say 32 metres. They are an irregular elliptical shape and look to have been infilled. I mused that they possibly be access points for some kind of chain/pulley system or cables. Or, possibly, these are holes left where brackets were removed, leading me to wonder if, due to the size and shape of this tunnel, it might have been created for vehicles of some kind. A niggle in my brain told me I had read about that somewhere. 

Well, whoop-de-doo – it turns out that Ian has already written about this subway here, although he hasn't made reference to Roadamant or the elliptical recesses.

Any further info is most welcome. 

*Fun with words. This is windy as in the weather, not as per a country lane which, on a blustery day, could be described as a windy windy lane or a windy winding lane. I am reminded of Windy Miller who lived in a windmill – Camberwick Green's opening credits feature a little character winding a handle to show each page of information. This should not be confused with winding a baby.

The names behind the letters on 161-167 Euston Road

I have lost count how many times I have looked at the building at the corner of on Euston Road and Upper Woburn Place, today occupied by Prezzo and Barry's Bootcamp, and wondered what on earth the letter N in the metalwork signifies. It's been on my To Do list for decades, so here goes... 

Here is the view from Eversholt Street with the portico of St Pancras New Church on the left:

Having just searched my archives for some pics of the details, it appears I have never taken a photo of this building, so all the images here are screen shots from Google Streetview. This is probably because I usually question the Ns when I have just gone past on a bus, having missed hundreds of photo opportunities. 

The next image shows the Ns within the fancy the metalwork, painted light grey-green. There is also a scripty B above the door to the restaurant at the corner:

The B is for Barclays Bank – I have seen Barclays Bs on other buildings, such as not far from here at 236-240 Pentonville Road where a second door has a letter T above it denoting Telephones/Telegraph office. They might well have had one of those 'You can telephone from here' signs outside. Barclays and the Post Office often occupied the same spaces. Coincidentally, here in Euston Road there is a huge telephone exchange next door constructed in the early 1930s (one of many exchanges in this area).


The view above, from the church across Upper Woburn Place, shows how impressive this building is. The elegant design continues on all three sides. At the corner of Endsleigh Gardens there is a similar corner door to the Barclays bank entrance but the embellishment contains no letter and has been painted black. A semi-circle of fancy metalwork is still in place:


At street level along Endsleigh Gdns there are elegant columned supports between which would have been, I am sure, display windows, today infilled with smaller windows:


At the western end the access for delivery vehicles is now also mostly blocked.

So, what do the Ns signify? 
Well, it turns out this was a company called Nettlefold & Sons, ironmongers. The company's address is shown as 163 Euston Road, today the entrance to Barry's Bootcamp, although I think Nettlefold's showroom and offices would have been accessed by the rear corner door.
Nettlefolds was founded at 54 High Holborn in 1823. They became famous for the quality of their screws used for boat and bridge building, manufactured in Smethwick. Almost 100 years later, in 1928, they moved to this Euston Road address which, I assume, due to its Beaux Arts style, was already constructed when the Nettlefolds arrived. 


The entrance to No163 later became access to the post office and Euston telegraph exchange next door. The 1939 directory shows that this door was also used by a Scottish life assurance company and Asprey & Co, goldsmiths.

N is for Nettlefolds. 
The strange this is, considering I have a bulging folder of photos of ironmongers' and founders' marks on coal hole plates, railings and bridges, I had never before heard of Nettlefolds until today, nor seen evidence of their work, probably because they made component parts often hidden from view.

Also, see the comments section below for how the company was absorbed into GKN – thanks Anonymous!
