Yours is almost an exact copy of my 27 treadle. Charlee is right, they take regular needles. Mine is about the same shape and has the same sphinx decals. I'd love to have a handcrank version. I'm cleaning up the treadle first and then working on the machine itself. Luckily I've got a really good shuttle and a bunch of bobbins and the machine sews well.
