Can you appraise it out of a book? Most books don't even list the 22" barrel except for carbine models, but this one isn't a carbine - it's a rifle.
To put it into perspective, out of all 1886s ever made, only about 8500 of them were made with a 22" barrel, and most of those were carbines - only 2213 of them were rifles.
But to consult the rarity table from the Madis book, in the first 100,000 of the 1886s produced, only 200 of those were carbines. My serial is 52,xxx, so given that rifles were more rare than carbines by a factor of 1 rifle to every 3carbines, and that my rifle is approximately halfway between 1 and 100,00, I've got one of about 30 short rifles produced in the first 60,000.
See what I mean? But the rarity is only part of it - the condition makes up the rest. I had a guy try to play up the fact that the barrel sights aren't original to the gun. In the grand scheme of things, it really doesn't matter and especially not since those sights are the earliest version of the #6 folding leaf sight and has been on the barrel for at least 100 years.
Probably not, I was using my "Blue Book". Oh oh, next page carbine in 22 inch ROUND barrel does not even mention a octo in the carbine. The "only" add for it is 40% for a full stock (very rare). Could it possible have been cut down? 95% on the carbine is at 15K! Either way, neat neat NEAT gun.
