Welcome to QB, Christine. I just tried my #3 disc on my 319 and it goes the correct way. There is another number on the other side 276303 and looks like the first link below. I downloaded a manual from singer.com and it says that for the model 288 that the blind stitch cam should be 350. It looks like the part number for that is 171340 and it looks like it would go the other way. As does the #32 - 276332.
Here are three links for flat cams that all say they are for blind stitch.

I have found that only the big red "Reply" button or "Quote" work to give me the paper clip icon to work for adding pictures.
