The bottom of the frame is shown on page 34 of "Volcanic Firearms: Predecessor to the Winchester Rifle" by Lewis & Rutter as an example of a later frame without a screw hole. It is noted as from the Donovan Williamson collection. It is one of approximately 1,200 No. 1 pistols that were manufactured by Horace Smith and Daniel B. Wesson in Norwich, Connecticut, in 1854 and 1855. They are historically significant pieces for both Smith & Wesson and Winchester collectors. The barrel has "CAST-STEEL" (right), "SMITH & WESSON/NORWICH CT" (top) and "PATENT/FEB. 14. 1854." (left). Factory floral and scroll engraving is featured on the frame, side plates, and hammer. The left side of the butt has "I 316," the right side of the lever has "316" and "I," and some of the small parts and both grip panels are stamped with "316". The lever is the later style without a spur on the bottom. Provenance: The Donovan Williamson Collection; Property of a Gentleman
