I just got a good deal on a K31 bayonet (Model 1918) at a company called "Collectors Source Military Collectibles" out of Canada. $35 and in excellent condition. Scabbard looks to be unissued, bayonet shows very light wear on the handle, nothing but scabbard marks on the blade. Looks like a good source for a lot of things. I picked up three British brass oilers for $10 each. Shipping a bit high but still a good final price all things considered.
