It seems I'm finding allot of knifes in the past few weeks. The top 2 are WWII fighting knives, marked "RH(PAL)36". The (RH) stands for Remmington Hunting, and according to my research, were procured by the Government for the troops in WWII. The one on the bottom is an Ontario 499 Air Force Survival knife, and I'm not sure of its time frame of service.
