300 Sun Helmet Prototypes were produced for the test, of which 100 had “felt shells”, 150 had “woven Panama hat shells” and 50 had “Gourd Sponge shells (also tested in helmet covers later in 1934)”. These were benchmarked against the standard army visor cap and also against the captured German Sun Helmet. Continue reading

I was actually finishing a new complete history of the IJA’s pay book, but due to the lack of one early sample to study and confirm a couple of details, I had to shelve the project for later completion and was in search of a handy project instead.
