Rare Russian Imperial S&W Model 3 Russian Third Model Revolver Tula

Very hard to find Russian Imperial Smith & Wesson Model 3 Russian Third Model Cavalry SA revolver made in Tula dated 1889 (the production of Third Model S&W started in Tula in 1886 and continued till 1897, about 40,000 revolvers made). Tula barrel address in russian, sharp acceptance and arsenal markings, matching serial numbers on frame (bottom of the grip), barrel, cylinder (unlike US made S&W Tula revolvers did not have serial numbers on barrel latches).
Hardwood grips are tight and in good condition. A lot of original blue finish (more on the frame, the barrel has some holster wear with brown patina). Great timing and indexing, tight lockup, no wobble. Function is fine. Great bright bore with strong rifling.
