I think I got this a few years ago. Maybe 1950s.
Where would you like me to take it on a date? I'd be happy to.
It might need a bit more cleaning for some fancy place, or to get a more serious answer.

These may help.
Earlier than 1950's -- much earlier. Probably mid to late 1930's because of the selector lever style and it also shows the patent number on the head.
Snapmon would most likely nail it down to the year.
1920-1944 if the logo chart above is accurate.
32-37, going by collecting Snap-on.
Wow, didn't think it would be that old! Now I'm really trying to remember where I picked it up.
