Identify this case
Has anyone come across one of these before? The story goes that a Jem PMC came in it from GC, brand new back in the early 90’s from the Sherman Oaks, CA GC to be exacf. I do have said PMC. My guess is that GC just put it in something they already had but I haven’t come across one of these before so thought I’d ask if anyone knows what it is? The only marks I can find is Cheney on the locks and Exelsior Standard on the latch, it is seemingly well made too. Thanks for your thoughts.
