JRH, Nice Sauer Daly drilling and by the sounds of it you did well on its purchase price. By the Serial number, your Drilling was produced around 1886-1887 or so.
Great info J,
Alright guys here is what we have here so far: The gun is a model 105, "Three Barrel Gun", made by J.P. Sauer for import to the U.S. by Schoverling and Daly of Manhattan N.Y. The gun was finished in the factory by an armorer with the identification "G" and was produced in approximately 1886-1887. The shotgun barrels are "Fine Damascus" 12ga barrels, while the rifle barrel is steel and most likely 38-55 caliber.
What I do not know as of yet: 1)What were the original chamber dimensions for the 12ga barrels. 2)Is the rifle barrel definitely 38-55, and if so what are the exact case dimensions. 3)What do the "SHUF" barrel markings represent. 4)What do the two "C circling R" barrel stamps represent. 5)Where might I find a competent gunsmith that can inspect the safety aspects of this firearm...
I must say...I am pleasantly surprised at the progress that has been made in such a short time identifying the different aspects of this gun. With a little good luck I foresee more great developments to come...
