Art,
About 3 months ago I bought this NIB Mauser-Interarms swiss-style luger in 9mm and with a 6" bbl. for $ 850.00 (from the Forum's Tom Heller).
I recently had another Fortum member (Hugh Clark) re-do the very rough factory grips to a great recheckering with the swiss-style border.
There are still NIB Masuer-Interarms for sale on the various gun and luger web-sites,...if you are looking for a NIB.
I decided, against some advice, to make this NIB luger my primary shooter. It's a great shooter, very accurate, and if I take care of it I won't have to chase replacement parts for many years...
I am also "hot on the trail" of an indentical luger that is also NIB, that will stay in my safe as such and maybe one day, collectors will place value on these lugers for the 1970-80's...
