I've been looking thru old trade publications most of the day and saw a "old ratchet" like that. I was going to take a screen shot and didn't. Damned if I can find it again

Hello, Oldgoaly. Sounds like my method of research!! Northwoods, if I flip it over does it become an LH12T :cheesy:

Haven't found the ad, but shows this in a service story from 1919

Wow that is a whole lot older than what I was looking at!
Some of the old blacksmith/wheelwright trade journals go back to the 1880's-1890's. The kind of stuff you do when it's too hot or too cold outside. Or in my case when you are having back spasms.

Hello, Bill. Thanks for the info. There are similarities, as in the slot for the pawl, and the gear. The one that I posted appears to be made from a solid piece of steel, and also has a cover plate for the gear. There is no evidence of anything being pressed together, it looks like everything wass milled into the steel. Thanks, Lou

I would guess they figured out it was easier or cheaper to mill out for the spring and pawl than it was to mill a precise rectangular hole to press fit that handle-spring and pawl combination.
