Hi Richard – thank you so much for your reply. I got this at Bracknell 5-10 years ago. It isn’t split frame – one set of wheels is live to the frame and the other has insulation at the hub. I had to replace this to get it back in one piece, and renew the oil-soaked fibre insulation on the insulated side brush, which was allowing a partial short. It also has new brushes from an XO4, and it works OK. It does have that aura of those pioneering days about it. Any further information gratefully received !
