to my knowledge Schmidt & Habermann was making the breech action guns and rifles for brenneke but of course in pre war times everything was possible in Suhl. anyone knows the english designation for the Brenneke action? in german it would be called best Stützhakenverschluß. you dont see it every day.

Schmidt& Habermann was making a lot of rifles for the trade but they were certainly one of the best makers in this time. this is what I remember here just know
