Singer 218G Sewing Machines
The Singer model 218G was one of the first models made at the old Haid und Neu Karslruhe factory in Germany after it came under Singer ownership in the mid 1950's. The 218G was a 'Singerised' version of an existing Haid und Neu model that had originally been based on the well established Singer 28/128 design.
The serial numbers for 218G machines take the form of the letters PA or PB followed by a sequence of 6 digits.
