I acquired one of these machines and fixed it (the bobbin winding gear was, well, crumbs but otherwise the machine is in amazing condition) and managed to thread it by trial and error. I really need a manual. I've found a few for sale but alas, I am a broke, no make that uber broke, art school student and my budget won't allow the expenditure. If anyone has one of these they'd be willing to scan in and send me or snail mail me (I'd pay postage!) I'd be so grateful. I figure this is probably a shot in the dark, but I'd really like to figure out how to use this machine properly as it has so many neat features that, so far, I'm only guessing at.
Riccar no longer has copies of this manual available. I've already tried :(
