I got, what I think, is a deal of a lifetime yesterday - a vintage Delta DP220, in dirty, but very good, running condition. I've been looking around for one for a while, a found it at an estate sale. I paid so little for it, I kind of feel guilty. I'm having a hard time getting an exact year on it. The information on VintageMachinery has serial number lists starting in 1942 or 1943 - those numbers begin with "13-xxxx". My serial number is "10-9204". My guess is its a 1940? That guess is based on a DP220 I saw on another forum that the owner claimed was a 1939 - with a serial number beginning "5-xxxx", and another the owner claimed was a 1940 with number beginning "10-xxxx", just like mine. My question is how these owners found the date of their pre-1942 machine. Not that it matters, but it would be nice to verify.
Secondly, aside from a thorough cleaning, I plan on replacing the 2 wire power cord with a modern, grounded, cord. Anything else I should look for or consider doing? Does anyone know of a source for a drill press task light of similar vintage? This one does not have one.
Thanks for reading!
