Are these Harvard or Mustang wheels?

BDK over on Wix thinks they are B-25 nosewheels – they certainly look similar.

Similar to but dont think T-6

T-6G Wheels

The manuals I have give the same style of braked for the G as for our earlier D. I’m not aware of T-6’s coming off a production line with Mustang style disk brakes, but it may have been a later modification by some users.

I’ve read that remanufactured T-6s…the post-war T-6Gs..were retrofitteed with Mustang wheels and brakes.

Since T-6G were supplied to many European nations (Germany, Spain, etc) there could be some laying about.

They look like my Harvard wheels to me.
The four posts are four the Zeus fasteners that attach the wheel covers

Mustang wheels aren’t split rim, thats why just about all Mustangs have P63 wheels.. which are split rim.
Those could be Stearman?

edit, not stearman..

Not Mustang wheels, Mustang wheels dont have the 4 upstands for fitting the hubcap.
