What is the closed length on those two knives?
The smaller one appears to be a 5464 pattern, which would be about 3 3/4" overall closed length. Made from circa 1955 - circa 1964.
The larger one was made around WW2 or before, as indicated by the tree on the reverse tang. Not sure about the pattern number, but Boker made a couple of similar congress knives before WW2.
Pattern 5474 is 4", and had a sheep foot and spear blade, but I have never seen evidence of this pattern being made before WW2.
Another option may be the 5974 pattern. It is 4 1/4" long, and was manufactured before WW2, but I have never seen one with ringed bolsters.
That one is a mystery. They are both beautiful though.
