Tracer, to some people the older ones are more "desireable", as to the fit and finish, more "hand fitting" etc,. gun craftsmenship, was considered "intensive" , thus costly and the companies always tried to "save a buck". I've had them both old and new, shot as well, but I do like the older bright finish better!
But bottom line it is condition, condition, condition that gets the 'big bucks' and packaging "adds" to the value.
A 'new in the box' will always go for more than a 'nice' older model, that's a GREAT shooter, has wear and no box.
I see them at shows all the time and yes, even the older ones in so-so shape, no box and they will be walking around for $550-650, but ANY year newer, and in the box ,mint shape ,they go for a couple of hundred dollars more. Unusual finishes, they will go over the $1000 mark and MORE! ( Now a Diamondback .22 caliber, nickel 6",mint in the box!)
How about double! /forums/images/graemlins/shocked.gif
