I picked these up from a chap in Nottingham yesterday, mainly for the Planet Jr disc set on it. However, I wondered if anyone could help with identifying the maker of the frame or if they have ever seen one before. It could also be homemade, but its designed and functions very well, leading me to think it could’ve been produced by a manufacturer…… My intention is to restore the discs to fit the tool frame of the Farmer’s Boy tractor.
