I found something at a thrift store I can not identify. They are sewing machine cams in a blue metal box (5 X 6.5 X 2"H). Inside are 3 rolls of 20 cams for a sewing machine. On the front of the metal tin it says, Pattern Discs. The discs measure about 2" in diameter and about one inch high.
Would any of you know what Sewing Machine these would fit?
Sorry, I can't attach a picture for you.
