Hello,
This will definatly change the price and collectors market. If it was sold in the US pre-war, then it is not a WW1 German piece. This changes the type of person who is willing to buy it and how much they are willing to pay. As for the price, we would still need some more pics.
I know the (very few) pre-war Canadian Broomhandles that were bought are extremely collectable and very valuable. This probably doesn't apply to your sice these were actual Canadian Military Pieces.
