Rear Speaker grill

[Greasyfingers]

So, as long as I've had my car this has been covering the hole in the back where the rear defrost intake would be. All the pictures, I've seen, the cover has been oval for the defrost. I have never seen a picture of the reverb speaker cover. Not sure if this original or what it may have come from if not. Any thoughts?

It fits really nice and looks better than a modern speaker grill. In the rear of my 66 barracuda.

For what it's worth- bought my '68 cuda new and installed a Motorola reverb. Bought a rear speaker from the dealer- it was a 6x9 oval.
