Caught my eye for sure.

Would like to know the history of the manufacturer.

I do know this much. Your's is somewhat dated by the Phillips Head blade of the medium driver. This screw head was NOT in use before the 1930's.

My example came from the abandoned estate of an immigrant Polish family that contained MANY items from the late 1800's to just post WW I, early WW II. MY example has an aluminum cap that was dyed red. Aluminum did not become viable for widespread commercial use until ~ 1890. My example does not have the Phillips blade driver.

This Family operated a large Butcher shop with several large trucks in Cleveland Ohio. They were also avid pioneer Harley Davidson riders judging from their photo albums. My tool was WELL used, perfect for an early HD rider, I'm sure.

Members of this family served in the US Army during the aftermath of the Spanish-American war (in a unit that had many trucks, cars and Harleys, as well as WW I, judging by the MANY images in the photo albums).

I'm estimating my example to be over 100 yrs old, from Europe, and WELL used by early Industrial Age American Truckers / Bikers.

Don't need it, how about you ?
