In response to your inquiry regarding other possibilities, you moight get lucky and find a Colt Model 1878 Double Action revolver (serial number below 39200, I understand, to be pre-1898) in a chambering which doesn't preclude it from antique status. As I understand it, the most common chamberings (.45 Colt, .44-40, .38-40, and some others) cannot qualify as antiques, but some revolvers were made in .44 Russian, .450 Boxer, .455 Enfield and .476 Enfield Â… if you could find one of those you'd be set Â… although being able to afford the price might be difficult.
Another - and likely much more affordable - possibility would be a pre-1898 Webley, either in a service revolver (Mk I through Mk III, or some early Mk IV's) or one of their non-military models. These are almost invariably chambered for standard British cartridges (.450 Boxer. .455 Webley/Eley/Enfield, .476 Enfield - all of which are actually .455 caliber, despite the varying nomenclature) none of which are on the list of proscribed cartridges for antique status. Alternatively, many such revolvers were altered upon importation into the US to fire either .45ACP in moon clips or .45 Auto Rim, but since those cartridges are not on the proscribed list either, such altered revolvers still qualify in Canada as antiques, if originally manufactured before 1898. It is
not recommendedthat such antique revolvers be shot with factory spec .45ACP/.45AR cartridges (because their standard operating pressures significantly
exceed the proof load pressures for .455 and related cartridges) but you can reload the brass to acceptable .455 specs.
I have several such British cartridge revolvers which qualify as antique in Canada, although by personal preference I have stuck with unaltered examples still in their original chamberings: top - (left) Adams 3rd Model and (right) Webley RIC New Model; middle - (l.) Enfield Mk II and (r.) Webley No. 4 (Webley-Pryse); bottom - (l.) Webley WG Target and (r.) WG Army …
