ejsxs:
I have a Ferlacher from 1948 too. It's not a shotgun but an o/u combo (BBF) by Franz Sodia. The funny thing is this gun in not coded. I checked another F. Sodia gun, from 1960, and that one is not coded either. BTW F. Sodia's code should be 33.
In other respects my 1948 gun is marked as expected.
My theory is that Franz Sodia, being by far the largest maker, allways marked his guns with full name and address so he managed to avoid the coding.
With kind regards,
Jani
