With the indulgence of everyone, I have a couple of KA-BAR knives that I hope someone can give me more information. The first is a fixed blade, 9 inches in length. The tang stamp has "KA-BAR" in the top line, with "REG US PAT OFF" on the second line. I researched that this would mean the knife was made between 1927 and 1945. But, can anyone help with the model of the knife? I do not know much about KA-Bars, but would this be something of a civilian type hunter since there are no USA, USMC, or USN markings?
The second knife is a stockman pattern, and what I have been able to determine would date from the late 60's to early 70's. The handles are wood, with brass bolsters and liners, pins. The tang stamp says "KA-BAR" on the first line, with "1109 USA" on the second line. I am assuming (and I know what that means!

) that the 1109 is the model number. Any other info anyone can shed will be most welcome.
Thanks for any help!!
