No, I have no idea. However, it's considered one of the most simplest made SMG's ever built. I wouldn't think it'd be much of a challenge to spot weld stamped sheet metal into a receiver. It's a very un-sophicticated design - even by 3rd. world production standards. There might be enough parts kits available to reduce the level of manufacturing needed, allowing for at least a minimum run of such a firearm.
I dunno, you're the guru...
If the M1 Carbine tooling was still available and not completely wore out or un-serviceable, it may be a viable product for the Canadian market. I think it's a great idea.
