Rca never made a 7316. It is possible, though unlikely, they put their brand on "real" 7316's which were only made by Philips in Heerlen Holland.
Philips manufactured several variations including a long plate w/ D shaped getter, long plate with halo getter and short plate w/halo getter.
True 7316's will have an etched manufacture/date code with a top line of Ct0 - Ct6 with the second line having a delta triangle and in the case of pre 1960 tubes a 2 character code and post 1960 tubes a 3 character code. ie; delta 9C or delta 1B2. And they were all gray plates w/2 staples.
Also you will note on all Philips tubes and most Euro tubes a cross hatch on the top of the tube envelope.
As far as real, genuine 7316's they must have those codes (unless they have been wiped) in order to 100% ensure they are the real deal. In the case of the codes missing then it's up to the buyer to rely on construction cues, which in the case of Philips tubes can be difficult.
To the original OP, if the codes are absent and the cross hatch is absent, then these are not "real" 7316's and even the seller may not have been aware.
If you are buying premium old stock tubes you MUST know what you're buying, what to look for and what questions to ask. Many sellers just parrot what's on the tube. Or in the case of old_radiola_guy, just outright lie and embellish.
As always "buyer beware"
