Diamond Calk Horseshoe Adjustable Wrench

Very nice collection!
In general I don't like doubles. I don't see them useful, no proper handle etc.
Nevertheless the idea is not dead, look at a brand new Wera Joker:

Neat. I think they're all far more novel than useful, but they look way cool.

O.K., my Double Diamond Calk Horseshoe Co adjustable wrench set is starting to come together. This is the 6”-8”. The last photo is with its older brothers, the 8”-10” double and the 10”-12” double. Now I’m on the hunt for the 4”–6” to round it out!

Nice. The oldest one is the 10-12 due to the USA After Duluth, Minn. likely late 1920's. the others are a bit newer maybe 1930's pure guess.
Good luck on the 4-6's old style.

I finally got a nice 4 x 6. It needed a little clean up and a new screw. For now I have a NOS Crescent screw in there. Slightly long, must be for a 6 incher.

You could cut the pin with a dremel and use a diamond blade and then put a new slot in.in the end carefully, I have done that. Might be way easier than trying to find a old style 4" pin.

Got this rusty frozen 4" at a garage/estate sale.



And cleaned up almost like new

My kid sister worked as a part time cashier in a local hardware store
They sold good quality tools, Diamond among others....
She used her employee discount to pick up a few tools for me

It's been so long, I am not sure which of these were purchased back then
