Thanks David, The left barrel is stamped L.C. Smith Maker Syracuse NY & the right Damascus steel barrel. I'm pretty sure it was made in late 1886. Its a 12 gage with 30 inch barrels. I have a air brush,so I thought I would use Dr. Bill's method of refinishing.I'm a retired tool maker so I have a lot of time on my hands. How do you refinish the checkering after its been cut? Paul
