Thanks for all the great info! The black one is a 66 according to the link above. I watched the video of the Brittish lady linked in a sticky in this forum on how to clean. My husband is out now buying supplies. I'm wondering if i should consider removing the screwed on motor and turning it back into a treadle. It's just a guess that it was originally a treadle since one of the cabinets has a treadle. Can anyone tell me whether the 66 came with a motor or maybe my great grandmother's original machine was a treadle and she just re-used the cabinet. The metal bobbin plate is missing. Does anyone know where i can get a replacement?
The 328 does appear to be a faded green. I wiped off some dust to get a better look at the color and some paint came with it :/ i took some more pictures with my better camera but am not having luck accessing them from the memory stick. I'll get my husband to figure it out for me.
There is a box full of attachments, mostly feet i think. I dont see any of the black disks that you described. I'll go have a look at those pictures.
