Well Harry,
I never looked closely after receiving it damaged. But as you pointed out it is '72. The base is dated '69 as well as the handset and ringer, but the dial and shell are '72!
Cool, I was born in 69 and my little brother was born in 72 so I've got the best of both worlds!
BTW there is a sticker on the bottom that says 6 72 so I reckon it was rehabbed in 72?
I have superglued the jigsaw puzzle back into place, now I will read up on cleaning and polishing the repair.
Maybe Ill start a new thread about the cleanup and rehab project. I tested it before disassembly and it transmits receives and dials like a champ, but doesn't ring yet. I'll get to that on re assembly.
