The tag is pretty dirty and messed up so it's hard to read.
"Look what I found!" deserves more than one photo. Photos needn't be pretty. Dirt should wash off of your tag. Looking at the tags on other examples might help decipher yours.
The chuck on yours is larger than the 1/4" examples I see online (which is cool). I am guessing that might mean it is later. Or, possibly higher amperage. What is the model number on the tag? Have you gained any insight googling elsewhere?
Based on the shape/style, I'd guess early to mid sixties. (guessing) I picked up a '66 CRAFTSMAN drill, (in spite of trying to exercise restraint... but the logo matched the saw my grandpa gave me). It is quite similar looking.
Before that one, I grabbed a Skill-Drill that I co
uldn't resist. As soon as I picked it up I was thrilled and said S
OLD!
The owner made sure the chuck key was always close at hand.
I believe the plug is original, because it is such a perfect match.
I looked at the Internet Archive site, to see if they had a catalog for the PET Co.. Nothing came up for Power Electric Tools Company.
I did find my drill in the 1947-48 Skil catalog ==

This drill cost $34 dollars then, which equates to $410 today. They offered it in multiple (single) speeds and custom speeds as well. I think the fact that it is so compact is what made it special. As well as the quality/type of bearings... and stuff.
The owner scratched AA in four places on this drill. The purplish dust matches some I found on a 10 inch bandsaw I'd purchased in the same store a week before. It's fun keeping two of AA's tools together. The bandsaw is a little bit older.
I try not to collect large things, like bandsaws, yet I have f
ive now. They're all very different! Drills are tempting because they don't take up much room and they are typically cheap. I'll try to get a photo of the CRAFTSMAN drill.
Here's the other drill I recently found. Not nearly as old, but attractive in so many ways. 3/8" chuck, variable speed, reversible, and prretty. The reverse switch is at the bottom of the handle... which is as long as the other one is short. I like the old Makita plastics. I paid a full $10 for that one with no regrets. I did shine that one up a little, but will leave the Skil Drill looking old. I did clean the dust out of it though.
I'll stop there. I like old drills.
