Hi !!

I also have an almost ( ???? ) finished Pershing. ( Do they ever get finished ? I think not. )
I am still working on some plastic surgery on my tank crew and also working up the nerve to install my metal tracks and sprokets.
I have a question that someone may be able to answer.
I notice on the top of the turret there is a circular impression with a rectangular slot cut in it.
Anyone know what it is ?
Leftover from manufacturing or actually some attachment point for missing equipment.

Thanks for any help.
