Some features:
An amazing never-before-seen early ad discovered by Dr. Chaulmontet that shows the 250 caliber family
The serial number chat is updated, based among other things on the dates we found on some base plates
The first year of production with double -framed logo is determined more precisely
Something exciting is also in there that will come to light very soon hopefully soon
