Thank you so much for responding, it's actually my cousin's other side of their family's grandparents or actually his dad's grandparents or great grandparents who found it, so I asked my cousin's dad if he knew anymore about it, and he said he is not sure exactly specifically when or where it was found, but thinks it was possibly found around Prince George or maybe Prince Rupert (and I think found outdoors, although I can't say definitively) and actually may have been found as early as the late 1700's to mid or so 1800's, i.e., possibly before the Transcontinental Railroad, which was 1860s-1870s. So although it could be a novelty sword, "if" hypothetically, it was found before the TCR, then it would be a little odd that there would be merchants selling swords for novelty purposes when functional purpose goods were in such high demand.
So provenance aside, if 'hypothetically,' it was found outdoors, and in Western Canada, pre-TCR, would this make a difference on what it might be? I thought it looked like a Ciquedea when I looked online at pictures but I honestly don't know anything about swords or daggers, or who would be carrying what kind out here. My cousin's dad thought it looked sort of Siberian/Asian or Russian, hence the Russian fur trader theory, but none of us actually know. We're all just curious about it, so were hoping maybe somebody might know. I don't know if any of this additional information helps but any info is much appreciated as it has always been such a mystery to everyone. They are not trying to sell it or anything, the family is just really curious about where it may have come from. Thank you again, I really appreciate it.
