My house was built in 1933 as part of a small private delevopment with a number of small crescents. The numbering was continuous around the estate and our house was on the spur from the main road. After 1945 (and a little rearrangement by the Luftwaffe) my road became prt on a new ring-road. The crescents were given individual names but the numbering stayed unchanged.
The result is that the numbers on "my" road now jump 76 places from the house next to mine, across the entrance to the crescents. Before the satnav era I got used to running out to flag down delivery vans and on one memorable occasion an ambulance (kidney stone, mine, 2am)
