This is a special cased pair of Klay-Colts. The set includes a serial numbers 25037E and 25038E completed for Colt by Frank Klay. The pair have been engraved in period engraving by Andrew Bourbon, Master Engraver and signed. The mahogany case is a match to the colt originals of the period.

Each revolver has my name engraved on the backstrap at my request. The workmanship is second to none and are a one of a kind presentation. Colt letter and Frank Klay's signed letter are included.
