Yeah, of course they do. Why did you ask them for an opinion about your legal, non-guns?
There was no paperwork to prove the guns were deactivated back in the day. Once they were no longer a gun, they were nobodies problem any more. Anybody could do it, and if the gun was a Registered one, you pretty much only had to take it to the local cops and they would look it over and the registration would disappear. Just another toy for the kids to play Army with, or Cowboys and Indians, as the case may be. Folks were not tied in knots about things that looked like gun, then. The whole replicas, etc., issue came to be with the new laws.
More details needed, to really suggest a useful direction to take. Just crappy, nothing special, guns, or potentially important relics and examples, or historically connected? The RCMP don't care either way. As a system, they pretty much just think of guns as 'bad'.
