Determing the age of an old skil saw
My girlfriend inherited an old wormdrive skil saw. I plugged it in and ran it for a couple of seconds and it sounds great. (I'll oil and lube it before it gets used) Anyway I'm wondering if anyone can tell me if it's possible to determine it's age? It's funny how little they have changed over the years. The one that I have been using for the last 25 years is lighter with more plastic but otherwise looks pretty much the same as this old one. I'm guessing the saw was built in the 50's but I'm curious to know for sure.
Any help would be appreciated.
