Well we both have one advantage now. My dad, who she taught to sew on it and also mechanically he watched and helped my grandad (who was a tacker (made shoes and slippers) on the same machine) maintain the machine and my gran taught him to tailor on it. My gran commissioned the machine direct from Jones' in 1952. They were sold in the UK as a Jones 283f. My dad thinks that somewhere in all the stuff from my grans he has the original docs. But I was unsuccessful last night. I managed to view a link to a 282 off the site and has a flashback to when I was 9 and my gran making me thread the thread through the hole on the clam holder for the spool. This was the problem with the looping and through trial and error last night we think we nailed it with the rebuild of the tension knob. I'll check it against yours though to be sure.
