You'll need to do a little more research to get an answer for this. The gun is certainly valuable, but there are a lot of variables. Features such as caliber, barrel length, the grade of wood the stock was made from all affect the value. First go to: http://armscollectors.com/sn/windates.htm and select the rifle's model number. This will link you to a page where you can enter the serial number, giving you the age of the rifle. Next, check out the on-line auctions, you can find them by Googling "Winchester 73" and "Winchester 1873". You'll find several auction houses including GunsAmerica dot com and GunBroker dot com, (these sites are easy to access and have lots of photos). You could also check out Cabella's, but their prices are generally high. Locate some rifles of a similar age and caliber and compare yours carefully to these. You want to check out the finish, how much of the blue color is left on the metal, is the wood in a similar condition. Most people buying Winchesters these days are collectors, and they're fussy. If the gun has been re-blued or the stock has been refinished, the value is decreased. Things like adding modern sights, or drilling holes to mount a scope also hurt the value. So look closely at what you've got. Once you've found a couple of rifles that you think are comparable, book mark them and come back after the auction has ended. Just because I'm asking $2000 for something doesn't mean anybody's going to pay it. This ought to give you a good idea what the gun is worth.
