As we still do not have a Finnish section i will post my newly acquired wonderful Finnish M34 SUUNTO compass here. I would much appreciate if i could get some more info on it than i already have. So here are the pics and info i have been provided. I am of course very interested in the specific year of manufacture
Upper left corner: The SA marking. SA=Suomen armeija= Finnish Army. They used this marking from 1942 - 1968.
Right below the SA initials, there's a circle with arrows behind it and number 7 engraved in the middle. That's the mark of the Weapons Depot 7. The was located in Iisalmi, Peltosalmi village (1944 - 1953) and then they moved it to Ähtäri, Inha village 1954-1992.
The letters PVT. It means Puolustusvoimain Taisteluvälineosasto (Defence forces ordnance organization).
The base plate says: "Patentoitu Suomessa ja ulkomailla" (Patented in Finland and abroad) and there are the instructions how to convert 60 degree system to 360 degree system.
