Doing a necessary gear purge, would like to know what to call these. They're heavy cast, aluminum, coated externally with some sort of concrete like high mass damping compound under at least 2 different paint layers. 1 inch throat, haven't verified the bolt circle dimension yet. Anybody?

JBL Radial 2350
Must be for a custom app, most have a separate throat adapter. JBL was hungry in the late 50's early 60's. they did a LOT of OEM, notably Westrex and Ampex.
Pair with drivers for reference:
JBL radial horns complete 16ohm 2470 2327 2328

I was wondering perhaps Ampex. They're a bit small for the 2350, but not far off from the 2345. My dimensions are as follows 5-1/4H x 21W x 15-1/4 deep. The one thing i keep staring at is that obround tab by the throat, it's very similar to the adjustable height/angle system that RCA used on their theater speakers.
I want to sell them. What would you call them?

I would say similar to JBL and post what info you have. It is possible that RCA bought from JBL, Steve would know. Those have the same to bumps that the JBL has. RCA horns don't.
JBL also made for Rauland, but do not think they are that. I m not saying they aren't. But 90% sure JBL made them.
IF I was forced into a guess, I find Apex likely. YMMV.
here is a supposedly complete list from the JBL site but it is missing the 2350
