Through a very generous RC community member I now have four in total, one of which is absolutely brand new and amazingly free-spinning. They are all slightly different internally, one having been modified with a full width middle spindle and a white nylon intermediate gear, another also has a machined alloy diff gear as opposed to Tufnol, plus two also have extended spindles which protrude from the gearbox casing. This suggests some sort of external drive to possibly a front gearbox, and sure enough, in the box of spare parts there is also a machined belt pulley. These items all came from a friend of Don Ison himself.
Extremely rare items which can now hopefully be rebuilt and put back into active service.
