hi -- I picked up a 404 model at an estate sale yesterday for a very small amount. It is a 1959 model. It needs a really thorough cleaning and some rust removed from the extra parts(ruffler, feet, etc). Can someone recommend the best site to order any missing pieces from? I think it's pretty intact but there is a small belt on the front that is rotting and the spool felts and stuff like that are in rough shape. I plan to use it for some heavy duty sewing -- leather and sunbrella -- if anyone has experience or advice I would love to receive it.
