Outlaw - The 1940 catalog shows two types of this model, an "All Purpose" with the single straight handle and no switch on the head. And a "Heavy Duty" model with 4 handles and a rectangular switch plate. (I learned something new tonight)
You're DP may still have been made later than 1936.
Plombob, you and I may have the Heavy Duty model.
7.5" - It's a 15" DP. That's the same as the 03622 model. I wonder what the difference is ?
This style of Atlas DP shows up in all the catalogs until 1944 where it's listed as
restricted. The 1945 and 1946 catalogs have no drill presses. The 1947 catalog has the new King-Seeley DP's.
I'm kinda wishing that we'd had this conversation over on the vintage DP thread instead of highjacking this thread.
