This is a zig zag white rotary model 765,serial number 18176, and runs great, no attachments or manual. Any info? and where do I find this info, Thanks.. also I have a couple of antique mach. I need info on, One is a Montgomery Wards long shuttle and it says model S40.. Motor says model E. Has manual and all attachments. Even ruffler and button holer. It does need the new wiring, with the three way attachment.I did check and it does run. It says the serial number is under the bed, where the wheel is, but I can not see it.there is a little piece of flat metal there but does not appear to have anything on it. Any help would be greatly appreciated. Carol
