The 2 blade looks to be a 125 gr Fleetwood deerslayer, from the late 40's and is quite common. The three blade appears to be a Hi-precision. It is a bit different that most were stamped with an "H" If you would care to part with one of the Hi-Precisions drop me a PM, I don't have an unmarked one in the collection. Marked ones are very common
