There are only 17 A-3 Grade Smith guns recorded in Brophy's serial number recap; but I've seen two other authentic A-3 Grade Smith guns not included in any grades recap, and I'm sure there are a few others. But you are not talking "apples to apples" as the A-3 Smith was a $750 gun at retail; whereas the LeFever Optimus was a $400 gun at retail. Now although the LeFever Optimus was one heck of a high-grade gun, the LC Smith A-2 was also a $400 gun at retail ($425 w/Hunter One-trigger); more than 200 A-2 Grade LC Smith guns have been recorded in various serial number recaps, and I've seen several other authentic A-2 Grade Smith guns whose serial numbers are not in any recap to include a unique A-2 to be featured in a future issue of the DGJ. And although the Lefever Optimus Grade was made for several years prior to the A-2 Grade Smith, and for several years after the A-2 Grade was discontinued; Lefever still did not produce more Optimus Grade guns that Hunter Arms produced A-2 Grade Smiths.
