Well I found out some information about the 1908 Mauser today, I posted this exact thread in another Canadian forum and low and behold, someone there knew the guy who built it, heres his reply:

The entire rifle was built by Kurt Hansen. He lived up here for many years and spent most of his time on Frances Lake, as well as in Faro. He was not a professional gunsmith, trapped mostly, but really enjoyed working on and building guns. His home on Frances Lake is now a tourist resort.

Now get this, the octagon barrel was done during one winter in the bush, entirley by hand, no machines at all! I well remember when he brought it to town in late Spring. He had it at the shop of one of the members here, Klondike Bob, and it was still in the white. Perhaps he will chime in here about this rifle, as well.

Kurt draw-filed the entire barrel and finished it with stones and emery cloth. He also did all of the action work.

This was just one of his projects. You should see the 98 Mauser he converted to a SQUARE BRIDGE!

Needless to say, I'm excited to know more about it than I did when I purchased it.
