I've just acquired a pfaff 1245 subclass 02/011. Anybody have a location for a manual and what this subclass means? Plus any more knowledge you should happen to want share with me about this machine would be appreciated.

It can do a 1/4 to 1 inch stitch.Also has a small shuttle. I'm looking at making a roller wheel based foot for it.

Ok, I've got a singer 7-11 ang a singer 7-31. Main differences, the Singer 7-11 has a reverse but no walking foot. Just to throw that out there in case anybody gets a chance to buy a 7-11.
