However mine is a 81 year with the older 2.15 Weinmann rim (same as my new spare wheel).

at .35" narrower than the 3.5" rim, that is almost 9mm narrower- a bit less than 4.5mm for for each side, 11mm to 15.5mm seems about right if they have aimed to centre the rims to the same point.

yeah it's a very difficult spot, that's why I used a socket as a gauge..then measured it's OD, works pretty easy.

on the earlier 2.15 wheels are the hubs identical to the later 2.50s?

had bought some unloved 2.15 wheels on fleabay for the hubs on the assumption that they did not change- but worth checking before getting some excel rims

0.463" clearance. I used a stack of feeler gauges inserted into the gap, then measured the stack with my digital calipers. Super easy.
