Quadruple headstamp indentification


#1

Hi, I have a casing with a quadruple element headstamp, however, it also has an additional marking on it. The number 5 is in the 12 o’clock position, the letter T is in the 3 o’clock position, the number 79 is in the 6 o’clock position and the letter D is in the 9 o’clock position. There is also a number 2 in the 4:30ish position. I have done some research and can not find anything or any information on a position between 3-6 o’clock.

Thanks,

Karen

Welcome here Karen!
Umm, how about an image of that headstamp?

It’s Swiss but that’s as far as I can go. Jack

Hi Karen,

Number 2 is a code indicating the cartridge was loaded using a primer with priming composition “1 b” elaborated in wet form.
