Occasionally bought old one, found seal on some parts that says 1972 year. See pictures.
Who knows its manufacturer, model and something useful about it - please help.
As I understand crank handle, carburetor and starting magneto were changed. Also I don't understand what for are 6 double-end bolts on the back (see back side picture).
