I obtained this knife in a box of antique corkscrews and the like. It appears to be a very poor condition Barlow knife used in advertising. Can anyone shed anything else onto this knife? Many thanks in advance.
I agree that it is most likely a Colonial but could be Imperial the blade is not the original main blade but is most likely the original secondary blade. I don't know of any Barlow that has ever been made as a single pen blade knife. Here is a Colonial that was recovered in stag by Glennbad.
