Found the following MK1 Welbike for sale , I'm curious about the engine number , did these differ on Welbikes early day's ? I've seen the following prefixes on Welbikes XXA which I believe was fitted to the early Autocycles , XXE obviously Welbike orientated ,and now XXF .
Could all these prefixes at some point have all been used on the Welbike .
Here's the link to the XXF listed Welbike ..... http://www.carandclassic.co.uk/car/C849852
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 .
