I remember seeing that box also and I recall it was priced high. The SCSW 3rd Edition doesn't mention any .22 short Model 46s and a S&W Collectors Association article doesn't mention any either. The presence of a box suggests some were produced but then agian the box could have been mismarked or even faked. If they exist, would they be called a 46-1?

Another rare variation would be the few factory nickel Model 41s which have been documented per SCSW 3rd Edition.
