The attached picture is one of a Ford 3 ton Derrick truck that I took several years ago. It is one of a bunch that were imported to the US in the 60s ex-Swiss I have been told as all the data plates are in German. I've found several all used by one of the big electrical contrators who did powerline construction.
At the bottom of the page below is couple of more pictues
