My brother gave me an Old Timer stockman back in 1970. I used that knife daily for nearly 25 years. Cleaned squirrels, rabbits ,fish and lots of every day cutting tasks. Then one day someone gave me another Old Timer (890T), so it replaced the first one. While cleaning out drawers I found the older one. Its derlin scales are faded. The clip blade is shorter and thinner from many years of use and is missing the shield. Using a magnifying glass I read the tang stamp for the first time. It read (JOHN PRIMBLE ,BELKNAP,IN USA 935). Were knives with this stamping common back then?
