I don't recognize it, despite the number of drills that I have, and the literature I've looked at. Of course, I could have seen an ad five years ago, and wouldn't necessarily recall it today. I
can tell you that the radial pattern of circular holes for airflow was used by both Black & Decker, and by Van Dorn, so that may be a starting point. I've got a friend who might be able to recognize it - but he doesn't use computers or the Internet, so it will be a while before I can show him the pictures. In any case, please do NOT consign it to the scrap metal heap! If you don't want it, PM me.
Is the right-side brush holder there? From above, it looks like it might be missing. Is the switch a toggle, or do you turn it to go from
off to
on?
Here's a Van Dorn with the holes:
