Looking for a BSA Golden Flash, A10, registration 419 ADF, first registered in 1961. I know it is still being taxed and was MOT'd up until 2018 (after which MOT is no longer required for it). Last sold in 2011. Grandfather has contacted the DVLA as a first owner to try and track it down but their records only go back to 1970 so they have no proof that he ever owned it.
