Well, I went and did it!!! Bought a Singer machine from and old feller--it was his wife's and before that his mother-in-law's. It is nice condition and came with a buttonholer, and boxes of stuff. But I didn't see a manual. It runs great and seems clean.
The Model is a 348, No. 81583-900 and made in Great Britean, AIN. Where can I find a manual for it? I did a search on this sight for info, but couldn't see anything about manuals. Will put up pictures when We have settled it in a spot. Came with at least 4 or 5 prs. of scissors, and two boxes of notions that I have not had a chance to look through! It's aqua and doesn't seem to have much wear.
