OK, just for the record, the following S&W top-breaks qualify as Antiques under US federal law:
- All single-action top-breaks, regardless of caliber, with the sole exception of the Schofield Model of 2000
- All Model Three large-frame double-action variants; although some models were not even catalogued until well into the 20th century, all frames are pre-1899
- .32 Double Action serial number 209301 and under
- .32 Safety Hammerless serial number 91400 and under
- .38 Double Action serial number 382022 and under
- .38 Safety Hammerless serial number 119900 and under
The .38 Double Action Perfected Model holds two unique distinctions: it's the only S&W top-break with a side-mounted thumb-actuated cylinder release, and the only vintage S&W top-break that was produced
only after 1898.
No .38 DA Perfected qualifies as an Antique.
The only S&W top-break that's not C&R-eligible is the Schofield Model of 2000, a modern reproduction produced by the S&W Performance Center. The last of the regular-production top-breaks, the .38 Safety Hammerless, was discontinued in 1940 and was not reintroduced after WWII.
