Is there anyone out there that can help me understand what these markings are on this Dutch Vickers. I know its been mentioned before but I don't think there was a resolve. I have looked for that post anD went through the FAQ and can't find anything. Any thoughts on C/15 and C/16. ?

Markings must be peculiar to Vickers; similar to workers marks on other lugers- JMHO.

Could refer to the steel type used.

I think Don and Vlim are onto something.
My lack of knowledge about the science of metal had me thinking in another direction however now this. the time frame is about right and could explain why some Vickers have these markings and some don't.

Robert L. Smith and George E. Sandland developed the Vickers hardness test in 1921 at the Vickers Ltd. They found this technique as they desired to have more simple technique than the Brinell hardness test for measuring the hardness of the material. The best part of the Vickers hardness test is that this test is applicable to all the metals that exist in the universe. The Vickers hardness test is expressed in the units of the Vickers Pyramid Number (HV) or Diamond Pyramid Hardness (DPH).
