I had posted about these wrenches on the old site but the mistery continued.
They're essentially car kit wrenches, but they work fine for me and they seem to have decent enough steel ( here's an example I founded listed as a Porche out wrench )
Gedore was a strong speculation so I did a bit of digging and saw no major similarities to any Gedore wrenches I found pictures of, Dowidat however was proving more and more similar.
Here's the best picture I could find of a pretty similar Dowidat wrench.
I could find no branded wrenches that were an exact match to mine, but Dowidats were the only closely similar examples.
I wish I could find an exact match with their name on it to confirm, but maybe they just didn't want their more refined standard production tools assocated with the much more crude kit wrenches.
I'd love to here any thoughts or ideas you guys may have.
