I suspect there are a few of them up here, but not many.
I'm not too sure about the value of this rifle in Canada, but here are some thoughts:
It seems average Arisakas with or without mums intact sell for more money in Canada than the U.S. because they are less common here. The same trend also seems to be happening with poor condition matching K98's selling for far more in Canada than they're worth in the U.S. However, the really high dollar top items seems to go for less between Canadian collectors than they would between U.S. collectors.
I thought about importing an Paratrooper Arisaka but was afraid I might not get my investment back if I was to sell in Canada at a later point. I would only go this route if this rifle was something that I absolutely must have and didn't care about investment. I doubt many people here would pay over $2000 for one of these rifles? Add your import fees, tax, shipping, and it might quickly become an expensive venture with little chance of a decent return.
These are just my thoughts on the importing of a Paratrooper Arisaka, for whatever it's worth...
I've never found one of these rifles in the local woodwork yet.
