This auction is for a Hornby Zero One Slave controller that has never been used. I originally intended to display this but I don’t have anywhere to put it. Perhaps it would be of interest to a retro-model railway enthusiast. A piece if polystyrene has broken away from the inside of the packaging and there ste a few scruff to the cardboard box. I haven’t been able to test this do it is sold as seen. Thanks for your understanding :) Thanks for looking!
