Does anyone know of any BR Std 20T Brake Vans which exist only in chassis form at any preserved lines? I know there are one or two around but can't remember where I've seen them. I believe one was damaged by fire but kept as a crane runner or similar. I believe that also there were a couple used as match wagons at Immingham for the ex BSC hoper wagons fitted with rotary couplers for moving them around in the depot when receiving attention. IIRC they had some additional handrails fitted so a shunter could ride on them and they still retained the handbrake column.
