for round bobbin rotary, I have: (I'm listing bobbin type, not all the machines that take it that I own)
Singer IF
Singer 15
Singer 66
Singer 221
Singer 319
Singer 115
Singer 29
( hmm, not sure if the Singer 72w19 takes special bobbins)
Pfaff
Viking
Bernina
Wheeler Wilson D9
White
New Home (old style)
Standard (but we determined a class 15 bobbin will work)
National
National Two Spool
Free
Sewhandy
Davis
When I get my shed organized, I'll do more to measure them and get the information posted.
Let me know if I'm missing any early Rotary - US made machines that take something other than what I've got listed.
