Looks like you're in the right area to be a Diamond fan!
Is that an Artsway grinder mixer in your signature photo?
It's an OLD Artsway ear corn special. No powered loading chute and the discharge auger sticks straight out the back. It has been retired and gets used as a spare now that I have a Gehl Mixall 170.
I think I might be a Diamond Fan. I've ran out of space to hang them all but my favorites are up there. Minus the 24" on the left all the wrenches are from the same vintage as the 18" you posted a pic of. On the right is a complete set of the last set of wrenches produced in Duluth. In the back is a set of the black oxide finish I'm working on. I'm only missing the 24" in that set. I know it was made I just haven't been able to locate one other in a picture.
I stumbled on all four of these at a local farm auction and couldn't pass them up. The bottom doubles are labeled "Diamond Tool & Horseshoe" but the letters are all stamped in and not raised like the rest of the Diamond tools I have ...
The KHT adjustables are early Diamond Calk wrenches and are pretty neat I think.
All the doubles and the oddballs.
I have a couple pails of doubles and other misc Diamond tools ... pliers, screwdrivers, tape measures and other types of wrenches that haven't been sorted out or displayed yet because I have no where to show them
