sorry, I registrated this thread very late...
@ pvon, yes, there are 9 models. But the proper Name is not "Field-Marshal series" as eg. Prinz Eugen never was a field marshal but correctly the "Commanders -Serie" (Feldherren-Serie).
Also at least one model (the "Roon") has two different kinds of the languet.
@ Bary Brown, wonderful, equal quality twin. What makermark does it have, the 33-41 or the later "squirrel looking over the shoulder"? and as the stamp says "DAMASZIERT" I think the blade is also etched.
