All About Pocket Knives

I recently bought a LF&C cattle knife, I want to date it. I was going to try to do this by the punch style. Does anyone know of good information on punches. I dug out a old Knife World with the article Punch drunk but this did not help on my knife. This punch does not have a pat. # on it, it is tang stamped LF&C. Thanks
