I think there is a snowball's chance in July of finding a spare set of barrels.
You would look a while to find another similar gun in Canada.
I believe it conforms to the specs of the 424 as listed in vintage books and catalogues and Wilson's Beretta history.
Couple problems with this gun as a 424: Cabela's shows a 424 on Guns International. It has a silver receiver (I'd call it more French grey than coined), and it does not appear to have a vent rib. I can't recall having seen a 424 with a blued receiver or a vent rib or a single trigger. Were all of those options available on the 424?
I'm hanging with the GR, or whatever variant of a GR might have been imported in Canada, or possibly brought back from Italy. We know they were offered with blued receivers, single triggers, and vent ribs.
