Bill : Did you mean a K/H stamp in your post, and not K/W ? If so. this may be the answer to the :raised ring". However, this then leads to the question "did K-H only supply the 15' wheels, oe did they also supply the standard 14" wheels" ?

Late to the after-party.
I should have said KW, not K/W. It stands for Kelsey Wheel.
Motor wheels appears to have supplied a large number of the 14" wheels.
