Here are some of my Swiss army instruments:
Left to Right:
1944 Recta 'matchbox' alloy compass, S/N shows it was made in 1944.
1943 Büchi marching compass Pattern 1932, has a 1943 inscription on it. (see middle photo).
1930s Lufft pocket altimeter, German made with Swiss property mark and silvered face (see lower photo).
1920s Büchi Artillery compass/level (GB Patt. 1916, Spanish Patt. 1920, Swiss Patt. 1929).
The 1943 inscription on the Büchi compass translates:
"My good friend Sgt. Major Ernest Roy, dedicated to the memory of common joys and sufferings with Combat Engineer Company 2, 1939-1943 Capt. Deller".
Hope you like them,
I'll do a more detailed study of the 1920s Büchi artillery compass later, it really is a nice intricate little instrument.
