I am guessing 20 to 50% but it depends on the gun and how badly someone else wants it. I should think that a Winchester with a 4 digit serial number would be a curiosity only (no increase in value), a 3 digit serial number would have a minimal increase in value, or maybe none, depending on condition, and a 2 – digit serial number would be worth a modest increase in value. I should think that the earliest known example would bring considerably less if not serial number 1, because if number 1 shows up, the earliest known example is no longer the earliest known example. Depends on the gun, the condition of the gun, how badly someone wants it, etc. Model 1873s with case colored receivers will bring a premium.A low serial number, especially number 1, or the earliest known serial number, would result in a several-fold increase in value, but difficult to quantify exactly. For Model 1873 with special features, it is best to secure an expert appraisal. Prices listed here are for standard guns only. In recent years, some of these special guns were sold at auction and brought prices well in excess of $100,000. Winchester sold only eight 1-of-100 Model 1873s and 136 of 1-of-1000 guns that were built.

For example, Winchester built two sets of special Model 1873s: 1-of-100 and 1-of-1000. Winchester Model 1873 was offered with a large number of extra-cost options that greatly affects the value of this gun. Winchester discontinued Model 1873 in 1919, after producing about 720,000 guns. Caliber stampings on Model 1873 are found on the bottom of the frame and on breech end of barrel. Upper tang was marked with model designation and serial number was stamped on lower tang.

Standard musket furnished with a nearly full-length forearm fastened to barrel with three barrel bands. Furnished standard with a rounded iron buttplate, straight-grip stock and carbine style fore-end fastened to barrel with a single barrel band. Equipped standard with a crescent iron buttplate, straight-grip stock and capped forearm. Sporting Rifle: 24" round, octagon or half-octagon barrel. Model 1873 was offered in three styles: 1.

Early model 1873s were fitted with an iron receiver until 1884, when a steel receiver was introduced. 22-caliber rimfire, with a few special order guns built in. Three additional cartridges were offered, but were not as popular as. 44-40 was the standard cartridge for Model 1873. With the introduction of single-action Colt pistol in 1878, chambered for the same cartridge, the individual had the convenience of a pistol for protection and accuracy of the Winchester for food and protection. 44 Henry, this cartridge was twice as good. Chambered for the more powerful centerfire cartridge. This is the "gun that won the West" and with good reason. This Winchester rifle was one of the most popular lever-actions the company ever produced.
