The where to buy parts for older and antique pistols thread

[Snake Plisken]

I can find a bunch of places stateside that have what I need, but most will not ship to Canada or the shipping cost is unreasonable. My google-fu has failed, are there no sources for colt, smith & wesson, etc parts in Canada ?

Looking for colt thunderer parts, smith & Wesson model 3 and Tokarev tt33 parts specifically

Thanks in advance
