this is one of the earliest surviving Bonds, number 196 of 25,500 , the 3rd oldest survivor . i decided that as i found , fairly early on ,an original unused red vinyl hood i would go for original spec. vinyl screen . he alternative glass screen necessitates making a different hood .r as i have the original early 122cc engine , rather than the 197cc most were upgraded to ,weight saving is a consideration also .as originally built it will "utilise " a hand operated windscreen wiper . thanks for the help i have emailed two companies and just wondered if anyone had a contact themselves .
