I'm looking for some help to identify this 20" wheel split bike , specifically manufacturer, model , age.
Here's what I know so far
hub is a sachs torpedo JET stamped "36" "R", frame splits in the middle and is of pressed steel construction . There are 5 rings stamped on the seat post adjustment ring , all other identifying marks and badges have been removed or painted over .
a serial number is visible on the left side drop out .
Any help with age or a guess at who the manufacturer is, would be of great asssitance . I hope to restore this bike , just trying to figure out where to start .
