Technical Part identification help needed

I know it's a front dash speaker for a '50s car (probably GM), but can anyone tell me exactly the year, make, and model it's for? Your help is appreciated!!!

Thanks!

Jim

 

That don't look like any factory install anything. I think it's a stereo store aftermarket unit. Show us the back side.

what HRP said.....

 

Not exactly, but it was a cheap one. The clock normally fits in the center.

 

I guess I've never payed enough attention to the Pontiac dash. I googled 51 Pontiac clock delete dash and here is what popped up. I stand corrected.
