It is the type that splits off the HV wire, I'm not sure of the blue gun position though. I will have to check when I get home from work, I'm getting ready to leave now. If the gun is in the right position, I'll give the swap a try. No matter what happens, both sets were free so no loss if if it don't work. I hope it does work however, it seems to me it would be an upgrade to the higher voltage focus. The donor set is a Philco Ford hotel set. I have another Philco Ford and the picture is beautiful. Maybe that sharp picture will cross over to the RCA if all goes well. I did try to restore then as a last resort rejuvenating the old CRT with my Sencore CR-70 tester. I always get great results with it except this time. Haven't tried the focus positions yet but that tube is really bad, the only gun working is the green, the other two are almost non existent.
