Been busy and haven't checked in for a while. On a little visit to a friends house we went junking and I got an old machine in a mission style cabinet. Was so happy to find it and DH has already fixed all the things that needed fixed and got the old machine running great. I also picked up a Singer Merritt 2404 at a thrift shop but it has only one cam. Can anybody tell me if cams from any other machine will work in this machine? I will so appreciate any info that can be offered.
