Mauro,
Here is the link to the page that shows the asking prices...another Mauser special luger is also shown for sale...
If these sold for $ 2000 or so when new, that is a nice investment for the original buyers...
I think I was spending money on girls in disco's during the 1970's...should have looked at these Mausers...
