According to the research and books written by Orchard & Madden, Peter Miller and Rob Van Meel, all Welbike engines are prefixed XXE. Ron

Thanks Rob , I was curious with XXF, first time I've seen this prefix .I forgot to mention I have also seen a Welbike with SER prefix possibly post war ? and blank no prefix or number .

I would imagine a few out there have had engines or cases replaced due to damage at some point .
