This is an interesting requirement because we know, for example, that Webley did not purchase any solid frames after 1893, however many of their solid frame handguns - like the bulldogs and MP's - were assembled well into the 20th century. But, since the frames are pre-1898, the whole gun is antique, no matter when it was assembled. The only thing you can't do is convert your antique to one of the calibers mentioned in the "exceptions" (.32 Colt and S&W, .38 CF etc. etc.).
This is why many shooters (especially now with that handgun freeze in effect) want an antique frame to rebuild - antique Colt SAA frames are popular for rebuild as a 357 mag or 38 Special. The parts you can buy from either Colt or one of the Italian reproductions makers are fairly easily made to fit, and there is nothing to prevent you from doing this - as long as you can prove that the ORIGINAL gun qualified as an antique. If your Colt SAA began life as a 45 Colt or 44 Winchester, all the modifications won't make it antique...
