Ok I uncovered my little jewel vintage Singer. She is a 1927 Model 66, SN AB724262. I will attach the pictures you've all been waiting for. I posted them on the regular board, but Janice said I needed to post them here too.
She is missing the spool pin for the thread, but I even have the manual that was revised in 1924, it was in the bottom drawer. She is a treadle, seems to work fine, I will clean her up and see how she sews someday.
Her she is 1927 - I need to name her
