The Model 1890 was produced in three distinct versions.
The first model had a solid frame, a case hardened receiver, and a fixed rear sight. Approximately 15,000 of these were produced between 1890 and 1892.
The second model was designed as a takedown rifle. It also had a case hardened receiver, but had an adjustable rear sight. In August 1901, the case hardened receiver was changed to a blued version. Approximately 100,000 second model rifles were produced with case hardened receivers, and 200,000 were produced with blued receivers. A deluxe version was offered, which featured a fancy checkered walnut stock available in either straight or pistol grip and a grooved slide handle.
The third model was also produced as a takedown rifle, and featured a modified receiver that allowed the breech bolt to lock externally. The third model was also available in a deluxe version, which, similar to the second model, featured a fancy checkered walnut stock available in either straight or pistol grip and a grooved slide handle.
As an option, there was a tang mounted peep sight.
Price jumps WAY up for the color case receiver, as opposed to blue. Blue version about $1100, color case about $3100. AND- with ANY collector's firearm, condition and originality drive the price.
