Not sure how old it is but guessing from the style possibly 1950's. Still fully working, threw a bulb in there just to test (was higher than 40W so it got hot pretty quickly) but that's the 2nd picture where you can see the light through it. Still moves and works perfectly well, can magnify and although I'm not sure how it mounts, I'm sure it does! It was in my late fathers shed and I cleaned it up a bit from the decades of sawdust but in pretty immaculate condition for the age! Please ask any questions before purchase as I can't accept returns on an "as is" item such as this. Thank you!
