Wow! What a wealth of information here. I just spent a l o n g time reading about 200 pages.
I am happy to be joining the vintage club with my "new to me" Singer 99k. I just got it at a junk shop for 25.00. All I needed was a new light job and some oil to get her going.
I have some Singer slant attachments if anyone wants to purchase them. Pm me.
