Anyone able to tell me how old this pocket knife is?

Found this hunting on base today. Base dates to the early 40's.
Thank you and HH!

Looks circa 1960s, does the little round shield say "Tree Brand"? If so it was made by Boker.

Thanks gunsil, nice eye! Scraped off the dirt and that is exactly what it said with the little tree emblem.
