My 1963 Hetchins Magnum Bonum had script on the toptube with the name of the original owner and his bike club. I have a photo of the second owner racing it in a two-up time trial in Britain. I'm the third owner, and I restored it to original two color paint scheme including the script for owner and bike club, plus some extras (chromed fork crown, seat tube panels, pained head tube). See
