S&W Model 657 .41 Mag; advice needed

[Oyaji]

Today I happened by a small gun shop about a 2 hour drive north of where I live. Much to my surprise and delight, the shop had on consignment a NIB Smith Model 657-4 with a 3" bbl. I have been wanting a Smith .41 Mag for years; actually would prefer a 6" bbl. Don't believe this revolver had ever been shot other than test firing at Springfield. It is one of the older pre-locks however, the firing pin is internal to the frame rather than on the hammer. Piece appears to be in perfect condition. Catch....it has a price tag of $800.00 on it. I made an offer of $700.00 and am waiting to hear from the owner.

What do you guys think? Is it over priced? Should I jump on it or pass? We don't see many of these Smith .41 Mags for sale hereabout.
