GB, that spanner size is 25/32 AF. Not common but can be found.
Thanks for that. I wonder why it's such an odd size.

That's a spanner which may fit, but early post-War Britain didn't use spanners with A/F on them as that's Unified nomenclature, and other than Lend-lease stuff still here, Unified threads would have been unknown, especially for a huge business conglomeration like BSA.
Weren't Rubery Owen another part of the BSA empire?

So that begs the question; what size spanner should it be?

I use the large end of an old BSA spanner marked 15 832. The tool list describes this as a mainshaft nut spanner. It measures about 0.8 inch across flats and given a bit of wear in it is about 25/32 inch.

Unified threads were not entirely unknown to BSA, the pressure relief valve thread being 7/8 inch x 16 tpi UNS (Unified Special)

Kokens makes a very nice little set of 3/8" drive Imperial sockets.
Also available in 12 point , if needed. The six point has less tendency to round off the bolt head or nut .

I have cut down many open ended spanners over the years for those specific (tight) jobs that seemed that the only other option was to remove the engine to get access!!
One particular job on the Matchless required grinding a spanner to suit as nothing would fit !!??
However , my whitworths are to expensive to cut in half  *eek*
