Do you know what weapons we used them in?
I can only think of a couple of 7,92 x 57 mm weapons we used after the war; Mauser K98k, MG34, Colt M/29. I’m unsure whether we kept any MG42s, but I’m relatively sure we had MG42-59s before we received actual MG3s.
The F1 variants of the K98k and MG34 were rebarreled for 7,62 x 63 mm (Coastal artillery installations and the Royal Norwegian Navy had original K98ks in 7,92 x 57 mm)
The M/29 was made with both 7,92 x 57 mm and 7,92 x 61 mm Norwegian Heavy-S chambered barrels. I reckon we used the same type of wooden blank in the Tung-M/29 after the war, as before and during 2. Vk.
I should add that the book «Norske mitraljøser og maskingeværer» has a photograph of a post-war excercise at a Norwegian coastal fortress. Two soldiers fire a Colt M/29 Lett 7,92 x 57 mm with a blank adaptor, using red plastic blanks.
My question can be rephrased to «did we use the blanks in any other guns than the Colt?»
