I am surprised that this gun carries a trap butt plate with it being a 1 frame. It looks original to me. Very rare in this frame size and condition, and a grade 2. The barrels being blued will hold it back a little, my guess is 2,000.00 or more. Very nice. Dave

now that you have taken the pictures, a next step would be to list it on the gunbroker.com auction site with a high reserve and see what the market says...i have been buying and selling on gunbroker for over 10 years. i have found their service to be excellent for determining the true value of rare and uncommon guns such as yours.
