I got this old single ring yesterday from my grandfather, you could imagine how happy i were. The only label on the razor is on the top plate, as you can see in the picture it says "Mond-Extra", i would like to now what model or year could this be, anyone can help ? It came in a rather worn Gillette case, got some vintage unopened blades as well. It is interesting that it`s in a Gillette case, because as much as i`ve done research, Mond-Extra made copies from Gillette, so basically it`s the same as a Gillette single ring.
Thanks for all your help !
Cleaned up really well :
