Well I've got another puzzler at least for me. Found this wrench today and all the marking it has are on one side E - 6165 D. B. 4 and it's spaced out about as I have spaced it. It's 6 inches long and the marking covers 2 3/8 inches. I was thinking maybe military because of the marking but was not able to get a hit on the internet with it. No sizes marked either mystifies me. I scoured AA and came up with nothing so here I came. TIA for any help y'all can provide.
