Back in winter I received an inquiry from a gentleman in US. He had a tank his father built for him in 1975 which had ceased to move and he asked if we could fix it. After consultations with Daryl Turner, our resident hobby genius, we agreed to perform the repair.
Here are the images of the tank as Daryl received it. The original build was indeed 1975. The transmission used dual clutches to move the tank and speed was a very simply electro-mechanical device, servo operated. The gentleman had installed a new radio with modern servos to control the functions, but the clutches after 45 years had worn out. The tracks, original from the kit, were in good condition albeit with the usual Sherman knock kneed idler problem plus a couple of the road wheels with their poly caps had decided to go on holiday.
