I've been following this very interesting thread.

It's not at all collectible as a Sauer.

It's certainly collectible as a Hagn, which it seems to be since it's on his website.

Going with that line we always quote around here..."buy the gun, not the name".

I certainly think it's a looker, I can't think that Hagn did less than expert work, not sure how much his name adds to the value though.

My problem lies in reconciling my gross habits with my net income.
