That's a 1938 model I think, G.E used a lettering systems to denote model year, I have a Canadian G.E that's a H-86, a 1939 model using an identical chassis to a Canadian RCA model A-6. The American G.Es used different chassis but the dating system was pretty much the same. It's a matter of personal preference of course but I also think that Canadian G.E sets also had nicer cabinets then either their American G.E counterparts or their Canadian RCA clones.
I think that the disks you speak of use two metal haves separated by an insulated strip do they not?
