I just wanted to show you my little Boerger family.
2 class cross is maker marked 22, the 1 class crosses are marked L/57.
The one with pin set-up has the caracteristic tube cross pin holding the needle in place .

I´ve had the 2 class for awhile, but have been on the search for a 1 class more than 2 years !!
All of a sudden I had the chance to buy both a pin and a screwback version, from the SAME man cool militariacool militaria
That really made my day

MFG
