WOW! Lots of rare features on that one, and condition too! Any 1881 with a cased receiver is very rare! That extra grade wood, pistol grip stocks, checkering, and the sights! Try to find a Lyman tang sight for an 1881, and a bare one will go for $250+!
Wish I had the money, but even at nearly $2500, it's not met his reserve, so I'll have to pass.
Sure a nice one to look at though! Thanks!
