No lining, Gillette logo on the bottom, single ring. Only odd thing I spotted at first was the inside frame and lack if a lining. Discovered by accident that the inside frame rotates out and presents the razor and blade cases when the case is stood up. I'm thinking it was for field medical or hospital use since the whole thing could be dropped in the autoclave and sterilized. I have had it for a while now but can't find any info at all.
Have shown this to a couple senior members but no luck so far on any history.
Find some documentation guys. This is bugging me.
Leaned back a bit or flat the frame rests in the bottom of the case.
Stood up the frame rotates out and presents the razor and blade cases.
Ps. another member here also has one a little different stamping on the bottom that came with no razor. He doesn't know anything about it either. Wear marks on my single ring seem to indicate it came in this case. Same with the blade cases.
Since I know you guys love a mystery. Got another one for you to solve.
