What you have is Model 1885 Single Shot Sporting Rifle, and it was originally shipped (sold) on June 7th, 1890.
As orignally built, it was a 22 Short with a 24-inch No. 1 octagon barrel. The records show that it was returned to the factory for rework on March 21st, 1908, and was apparently rebarreled to its current configuration (it should have a 28-inch barrel, no. 1 size).
