How about this early wood rim slightly dished 14" moto-lita!!
Or a 13" leather one!!!
Whatever you go for make sure it is a dished wheel!!
I have fitted,glued on a p5 steering wheel badge in the middle!
The 3D rover shield,ship,head emblem,as the std P63500 auto badge is boring!
The 3500S badge can be made to fit with a little backing plate and glue!!
Just dont use the super strong stuff,so its easy to pop off if you need to take the wheel off at any point!
I dont think you will find a wheel that you can just fit the existing badge and its mount to! You will have to adapt it!!
Moto-lita do,make a wheel with a smaller centre and boss but they look too small to fit the 3500S badge to!!
If you get one with a horn push like the TR6 one,!!! You maybe able to remove the hornpush middle bit and stick the 3500S badge in there instead!!
I got the 14" wood wheel off ebay for £25, and by pure coincidence/luck!
I bought a new boss for £15 from Ebay the next day!!!
The leather one in the TR6 was £10 from an autojumble with the boss and badge!!! Bargain!!
