A very nice find, Skip. Always interesting to see an unusual tool marked with the Ford scrip. Around my neck of the woods it's not unusual to find tools and such with the Ford mark. Your drill does not have a commercial made look. It may have been shop made at or by Ford. Maybe a project by a Ford tool maker apprentice, or Ford trade school project.

PS, I just found a nice Brown & Sharp 12 inch vernier depth gage marked Ford at the flea market last week. I post soon.
