I think you may have taken the info from the motor. Flip up the machine and look underneath. There should be a serial number and a JA number. Since it is a Japanese machine it was made after the 50's. National was a domestic sewing machine company and made all Montgomery Wards' machines until the 50's.

vintagejapanesesewingmachines Yahoo group has a lot of info in the files regarding Japanese sewing machines.

I would like to know the year of model 188 serel number 55X URR188AB If you know any thing about this please let me know
