KEEP!
This was not as common as the normal utility, its a 75-75 Victa special 160.
It will need a fair bit to restore, but its not an easy find, and quite a nice machine when done up!
All you need for that is to tidy up the base, and shove a working Series 70 MKIV engine on it (Full Crank, Starter on top, Plastic Carby) and a fresh LM carby, and your on the path to a restore.
Any cracks in the base plate itself?
