This car (LHO 401) has been described in this forum before. It is coming up for auction in the H&H auction in Duxford on 9th October

This was apparently owned by Derek Cunningham for many years and there is a Motor Sport Magazine article from 1956 that mentions it. I think I saw it in the carpark at Goodwood this year looking very shiny. If it only makes the guide price then I think it will have been loss-making for someone in a very major way!
