You have some of the best flea market finds 
I kind of think that it's because there is little interest in model engineering in Canada, so a lot of stuff ends up in flea markets and yard sales.
Until 2007, I lived in a small city some 50 miles north of Toronto, Ontario, and found all kinds of stuff at yard sales and flea markets. Since then, however, I have lived in a farming community of about 2500 in eastern Ontario, where there are about 1/50th as many as sales, but it's still amazing what I find out here in the boonies....
Seek and ye shall find, say I.
