I am considering pulling out like 20 big black bags

[JB5pro]

floor tile scraps, debris and lots of dust out of huge dumpster to see if I can find the chassis to this cabinet. I think the chassis is elsewhere as I pulled out alot of bags and stuff already. DOes anybody know the likely chassis it would have had? It looks like mid to late 70's RCA to me. If someone knew the likely chassis I would be more likely to look more for it.
I will use verneer from the top to replace small section at lower side of my '64Antionette that is missing and the screws can give me exact replacements for a few missing ones on the back of my '72 RCA hec.

Thanks, John
