No: S 26431

Here we have a WW2 era Compass by SUUNTO Company from Finland. The compass is liquid filled and has leather strap. This compass  is  marked S 26431.

This type compass was used in the Finnish army during the Winter War (1939-1940 )and the continuation war.(1941-1944)

Two companies produced it, o/y Physics A/B Helsinki and Suunto Helsinki.

After all this time these compasses still work properly. Only the fluid became brown. But they never leak.
