Anyone know the correct rim off-set for a 1961 AJS Model 14 ?

I've never had a lightweight but AMC were usually central ie no offset. Must be someone who can put a straight edge across their rear wheel and measure it??

I measured these tonight & thought they might be useful for someone else:-
I acquired these wheels 8 years after they left the factory & have stored them unused & unmolested for the last 52 years. The rims are very true & without wobbles. I am pretty sure they are still as they left the factory - apart from the rust, that is!
Offsets measured with a straight edge laid across the mouth of the brake drum – distance between straight edge & rim.
Wheel Rim off-sets measured for 1961 Matchless G5 350cc Lightweight:-
FRONT WHEEL RIM = 5/16 inches
REAR WHEEL = 1 & 5/8 inches (Spot on - all the way round!)
Wheel Rim off-sets measured for 1961 AJS Model 14S 250cc Lightweight:-
FRONT WHEEL RIM = 11/32 inches
REAR WHEEL = 1 & 11/16 inches
The width of the above rims measured was 2 & 3/4 inches in the case of the 350 front rim and 2 & 23/32 inches for both the front and rear rims on the 250. Modern pattern replacement rims widths may be different from these in which case the figures I have given for offsets would need to be adjusted to take account.
