Let’s see if I can get these photos to work!

Quick search and I saw this!

Thanks, I think DRGM stands for (german words) meaning that the product was registered within all of the german states, started in 1891- 1949. This was similar to a copyright. So, I don't think that refers to a brand.

The Drpa stands roughly for patent applied for. So, I don't think the markings refer to a brand. I feel like I found something about these being around in WW1, but now I can't find the info!! UGHHH!

Strictly opinion, but WW1 seems early for hex ratcheting box ends- after WW2 sounds closer to the era.

Thanks, I wasn't sure about that!

Looks as handy as the Dunlap set that I have. Wonder what the internals look like?

Check out patent # 2500835 Feb 1947. I have both MAC & Powrcraft ratcheting box ends with the number. Technology seems the same on Craftsman, Dunlap, etc.

Similar markings, don't know what "Chete patent" or "RAT" stands for. Cheers
