Thank you very much! That is very interesting. I'm looking for post 1948 renumberd vehicles too, like the R series(RA-RH), Y series(YA-YZ), X series(XA-X?) and Z series(ZA-Z?). I'm grateful for every page I can get.
can anybody help me please with the registrations of old motorcycles?
Are 35YB12, 08YB71, 18YA69, 51YB13, 70YA81 and 81YA81 Ariel W/NG and are 30YD61, 66YC85, 48YD37, 52YD89 and 15YE16 Machtless 3GL?
