its time now to make a little inventory with the rifles we have see

serial number 136 8x60S
295 7x57
430 10,75x68
636 10,75x68
682 8x60S
692 8x60S
1303 10,75x68
1465 10,75x68
1498 10,75x68
1866 10,75x68
1940 10,75x68

without number 10,75x68
unknown number 7x57

this are 3 rifles in 8x60S, 2 in 7x57 and 8 rifles in 10,75x68
it seems my first idea that the 10,75 caliber was the rarest variant is not true but on the contrary its the most common caliber. this model was build from 1947(maybe 1946) up to 1951 but it could be parts were made and the rifles were fitted on demand also some years after 1951.
