I agree with Ephemerald. I also looked at that caseback and said, "has to be Guildite", when I made my initial post in this thread. It has the "look" about it.
I've definitely seen mistakes in case markings from this period, but I've never seen anything as wrong as this marking would be, if it is wrong.
For the record, I once found a Gruen from this era with a Guildite back that was magnetic. Not only was it attracted to a magnet, you could pick it up with an unmagnetized screwdriver... needless to say, that's atypical behavior in a stainless steel! The movement would run out of the case but not in it, and it took me forever to find out why (since I "knew" that Gruen's stainless steel is nonmagnetic). And then forever to fix the problem - I ended by blowtorching the case back to anneal it, which finally worked. Never found anything else like that one though. I wonder what happened to it to induce the magnetism in the first place.
