Marked "7" outside, 4 rivets (source IMM: article C.von Tettineck) Marked "7" outside, 4 round rivets. It seems that itís an early manufacture, which is knowable by the catch system. Examples seems to have been produced with no mark. The catch is soldered to an oval piece of metal. The hook is of a flat square section.
