I visited a LGS I hadn't been in for quite some time today. They had a very nice 6" N serial numbered 28-2 in the case, and right there in plain sight was a price tag for $800 stating it was unfired.

Light turn ring, no box, no papers, no tools, just the gun, and if it's unfired, I'm a banana.

I wouldn't mind having a 6" to go with my 4", but a 6" at double what I paid for my 4" isn't going to happen right now.
What can I say.[/QUOTE
WOW you paid $400 mine was $145 new in the box. It was my first Smith and I would not sell it at ANY price.
That was 2 weeks pay for an E-4 then. Now I can get one for a weeks pay. If I still worked.
I saw a beater M 15 at the gun show $425 Way high and well used. Not a deal.

A M-12 4 inch at $350 85-90% tight but finish worn a bit.
Moral is you can ask anything.
Looking for a fair deal is part of the fun.
