It’s amazing how many different types of street signage there are out there. Here is just a small selection of the ones made in metal/enamel. I am particularly interested in the really old ones that only use a London area code, such as N or E and I have been fortunate to stumble across quite a few in the Lower Clapton area that have the old NE postal region on them. NE was phased out in 1866 when it became part of the E region as shown here by Sewdley St NE right next to Millfields Road E5. It is also interesting to note the changes in punctuation on these early NE signs; some have 2 full points (perhaps signifying a colon turned 90 degrees?), others have a full point and a comma (semi-colon?) and others just a comma, yet Clifden Rd has none of the above.
