Cool old drill rig. I really like these things. In fact, I have a setup like this, only an earlier model.
Too bad the seller didn't take any closeup pictures of the name plates on the drill and the drill stand. Although, that lame Wynn's crossed-flags sticker on the drill would most likely obscure the information.
My guess is this unit consists of a Black & Decker 1/2" Special Electric Drill with a Model B Drill Stand from the mid to late 20s. The Model B Drill Stand is a bench-mount unit. The wall-mount unit was a Model D. The name plate on the drill would most likely list an April 29, 1924 patent date.
I have a copy of an ad from 1928 that shows this exact drill. Also a catalog listing for the Drill Stand dating from 1925. The drill was advertised at $48. The drill stand was $28.
Adjusted for inflation, those prices today would be $656.50 for the drill and $382.96 for the drill stand. While these prices might seem high, one has to remember that equipment like this was marketed to industry. The consumer **** didn't hit the market until much later. At the time these drills were real labor-savers in factories, on construction sites, in mines, etc., and companies were willing to pay the price.
One should also note that these drills were quite powerful and heavy. However, those were the days when men were MEN. Although, I imagine they used tool balancers in factories to ease the operators pain. Also, this drill is a prime example of an arm breaker and a widow maker. No need for a girlie-man grounded power cord back then.
As I mentioned, I have a unit like this. Mine's a 1/2" Type K drill and a Model 1 drill stand. The drill has a patent date of NOV 6, 1917. My drill is much cleaner and it works great. I also put on a new GROUNDED power cord. And, no, I don't wear a skirt. One of these days I will document my drill on here with text and pictures. Perhaps do a write up on my Norwegian Arm Breaker too.
FYI, there was an April 24, 1921 patent too. I think I've seen pictures of a drill with this date.
Anyway, great drills! Too bad Black & Decker doesn't make quality stuff like that today. I mean, my drill is over 90 years old and it works like a charm. Doubt much of today's stuff will last that long.
