Great link and article. Cheers. I'm a fan of the M1950 compass. I own and use a Cammenga H3 model balanced for use down here in the Southern Hemisphere. It's a shame the report didn't go any further back than the M1938 model of the WWII years. The daddy of the M1938 was a British patent liquid-filled marching compass circa 1910s.

It's a shame the US Army didn't stick with the WWI-era prismatic compasses they issued near the end of the First World War. They were, and still are, some of the best compasses around. I own a British-issue one and use it out bush any chance I get. It turns 100 years old next year. One of the WWI-style Prismatic compasses, evolved with an induction dampened card like the later model M1938s and the M1950/current-issue Cammengas would have been the perfect marching compass.

This was my 1918-manufactured, Swiss made, WWI US Army Engineers Corps Verner's Pattern MkVIII prismatic marching compass before I sold it for an Aussie one. One of these with induction-dampened dial would have been the perfect military compass. Hmmm... I wonder how hard it'd be to ... never mind :-D
