Hmmmm !!!
Hi Flying Blind,
Had a look through my Dunlop List and nothing with that number. My list covers 1930’s through to 60’s military (UK ) and some civil. Only have one AH Number starting with a 7 too and that’s AH 720 (Dragon). Have to concur with other replies about check that number to make sure it’s absolutely right and /or look for other numbers on main hub. What size wheel do you think it is ? It looks (Loose Flange and locking ring assembly ) like anything from WW2 through to late 1950’s. Hope you get to ID them.
