I bought this with a group of old pocketknives. It is a Case XX Stainless USA, model M279, and made between 1965-69. "Owen-Illinois F.P.D. Circleville Ohio", is what the handle is marked, . Here are my assumptions about this knife, it is a service award for a Owen-Illinois employee, who may have been a fireman or policeman? What I did find out , was the company was supposely the "wood or timber division " of the bottling company. Now my question is, was this a manufacturer of the shipping crates to ship the bottles? Haven't had many unique bottles to post here lately, Our diggings been sparse this year, regular rains fell nearly all spring and summer, and the ground is still completely saturated, however, had two great relic (CW) hunts earlier this year and one good surface hunt for native American artifacts!
