What kind of primer pocket swager is this?

I picked this up off of ebay, looks very similar to a CH4d but the "ram" that shellholders snap into is marked RCBS. Did RCBS ever make one like this? It seems to work pretty well just testing it on a handful of 223 brass

I have an RCBS unit, but it looks completely different than that one. If you don't get an answer here, maybe sending a photo to RCBS's customer service people would help.

That looks like the adapter to use RCBS shellholders in am old C & H press.

I agree with witchhunter. I think it's a C&H that's merely using a RCBS shell holder.
