Smiffy. I know Wiki state September in 1930, followed by someone's book- taking the lead from Wiki? But there is no doubt at all in my mind that I travelled along Gillingham High Street on the open top deck of one- noisey, rattley, drafty but exhilarating- I can even imagine it now and I don't need to close my eyes! And I was born in April, 1930, so, just for the record.
