Here is a close up of my Singer model 99-13,That's the model number on the book I got with it, as well as all of the attachments. By looking at the worn decals on the front of the table, it looks like it has been used a bit. It still works fine. But when I need to do alot of sewing or need a fancy stitch I have a Singer Confidence 7469... it is not a bit as strongly built as these old ones. I seen one of these for sale on Ebay, and it showed it sewing up to five layers of leather and quite a lot of heavy duty work... The sieral # reads AD626938. any help on knowing about it would be great. Even if it's not so rare...I think I'll keep it. I allso have a portable. Sears/Kenmore model 158-10301 Serial # 0027654. It's in a white plastic case with molded in roses on both sides, It was given to me and it doesn't have the cord with a plug or foot switch. any help or needs for this as a parts machine
