While these are cheap and available, there are fewer of them in Canada than you might think. Carcanos have not been a popular seller in Canada historically.
When these are gone, they will appreciate. Like all milsurps have, apart from those on the ban lists.
That said, I've been hearing "this may be the last of theilsurps" for 20 years. Then something new turns up.
I'm not prepared to say this is the end just yet.
I think there are more cahches of stuff in places like the Baltics, Asia, India, and Africa.
No idea what might be next though.
Hell, 15 years ago the Nepal cache was put up for sale and all of a sudden Snider's and martinis were everywhere - certainly nobody predicted that in the 2000's.
