Please help identify this hub

[900triple]

Hi,

Can anyone help? I have this hub and I don't know what its from. Can anyone help identify it? Ignore the leading link forks that it's attached to - they are home made...off a 1960's scrambler outfit.

Thanks in advance - this one has me really stumped!!!

well the brake plate looks like a late forties/early fifties Triumph item with a good deal of the anchor arm sawn off.
But the matching hub would not have had cooling fins or knockouts....
Is it seven or eight inch diameter?

I disagree about the ribs

it looks like a 8 inch T110 front brake with the lug sawn off

Could be - the engine which was in the frame (a BSA GS frame) was a T110.

no it don't, sorry!

the T110 from 1954 had an 8inch front brake with ribbed hub - in that you are correct - , but the backplate looks different. It didn't have the raised surround like in the picture but its outer surface was plain instead and it had two air scoops.

@900triple: It really would help to know the brake drum diameter, though.
If it is 7inch then you most likely have the standard 1946 to 1953 Triumph backplate in a yet unidentified hub because to my knowledge Triumph never made a 7inch ribbed halfwidth front hub.
If it is 8inch then it might be a standard Triumph hub as used from 1954. Triumph made no 8inch front brakes for its road models before 1954 and when it finally did the backplate looked different as mentioned above. There was, however, an 8inch front brake in the GrandPrix racing model from 1946 to 1951 and its backplate looked like the one you have. But only about 250 machines were ever made so if your wheel is really off one of them it would be a shame about the sawn-off anchor arm....

Cheers

Thanks for all of the replies so far. The brake is 8"
Here's some more photo's.

 A good point about the  GP brake plate esometisse, it could well be the answer as that was the sort of butchery we all did back then when "specials" were the thing to have.

Looks like a BSA hub to me with a different  brakeplate?

Any ideas what BSA hub it could be?

This is certainely NOT a BSA hub. BSA did make 8inch half-width hubs, of course, and in several versions,too; but these are quite different to the one 900triple has.
Main differences are: -Hub and drum were never bolted together but riveted for the pressed-steel drum or brazed for the cast one.
                             -If they had ventilation holes or knockouts, there were 6 or 12 of them, never 10.
                             -If they carried cooling ribs (GoldStar and A65), these were outboard the spoke flange, not inboard.

The Triumph GrandPrix is still your best bet so far

Thanks for the photos - looks identical to me even down to the small indent in the plate beside the spindle hole to clear the mudguard stay nut...
