Pontiac trim - big and bold 1950's style

This is a NOS trim piece that I got with a lot of 1930's to 1960's parts. Looks to me like it is from the early to mid 1950's, but would like to know the exact application.

There are no identifying numbers on either the metal housing or the plastic insert. It is about 9 inches overall diameter, so seems large for a grill or interior trim part, but I don't think it is a hub cap unless it fits into a larger ring of some sort.

Hope someone can identify for me. Tom

looks like the radio speaker block off plate from an early 50's Pontiac dash ...

from 1953 to 1956, pontiacs had an optional wire wheel hubcap, this is the center cap from the 1954 version, the center cap covered up the mounting basket and wheel's lug nuts, charles coker, 1953 pontiac tech advisor, hey tom, is it for sale ?

Thanks for the identification on the hubcap I'd never have guessed since I didn't know that Pontiac offered the wire wheels in those years - only have seen them on Cadillac and Buick among GM vehicles.

Here is perhaps the world's most famous mid-fifties Pontiac convertible,
