Driving back from Hungary, I took a detour to Suhl in Germany to visit the weapons museum. It is excellent. If you like/are interested in Merkel, Sauer, Schmeisser, you name it, then this is a good place to go. When it was still East Germany, the town employed thousands in the firearms industry. Now there is really only Merkel left as a medium size employer. J.P. Sauer, which started in Suhl in 1751 is now hq'd in Eckernfoerde in what used to be W-Germany. Suhl still has quite a few gun smiths?manufactures where you can order custom work. Lovely stuff, really nice. I am so so tempted. Luckily (or not) the shops were closed when I was there.
One part of the exhibition was about the gunsmithing school and their apprenticeship system. It looks a really sound system. There was a little girl (I am old) at the museum who was a apprentice engraver and working on a sideplate. Nice work, not like some of the germanic stuff which can be a bit ott.
Anyway, it's a good place. Go there if you can.
