I forgot I had this :). Not really, just didnt' think of it in terms of vintage until I saw someone mention 1975.
My bosses dad gave me this and the cabinet it came it, right before his wife died 2 years ago. He died a month later.
At the time I messed with it a little and couldnt' get a decent stitch so I put it away. I kept trying to find information but i keep coming up blank.
A couple months ago I got her out and cleaned the bobbin area and oiled her really good. Messed with her all night and finally got her humming and producing and awesome stitch! This led me on a search again and somehow I found this virtual vintage shop :)
The receipt says 9/18/1973 (YES, I have his original receipt!) and I do not know if he bought it new or used. I'm guessing new. It is a Domestic 816 Green. The S/N is 2111. I can't find a manual on THIS model :(
Anybody know any thing more about it?
