This Delta Specialty Company number 620 "double duty" model drill press dates to between 1931 and 1936, according to the catalogs on this site. The keyless chuck was introduced in Delta's1933 catalog, and Delta replaced this design with a new home shop drillpress with the motor at the top in the 1937 catalog. This one has a lug on the left hand side where the task light shown in the 1936 catalog could be mounted; the lug is not present in the 1933 catalog. However, the decal design was on a 1929 catalog, but seems to disappear from the 1930s catalogs, as does the name "Delta Specialty Co."

The head is cast aluminum, while the table and base are cast iron. This one was repainted to this lovely public works-truck green. The person I got it from said she thought her father (80 years old in 2004) bought it new, but he would have been between 9 and 12 years old, so I don't think so. The motor is a later GE 1/4 hp. It's in good condition, but the works are a bit sticky so it's due for a good cleaning. I don't think I'll repaint it just yet.

I haven't found a serial number on the machine. It cost $16.95 in 1933 and $18.95 in 1936, motor not included.
