I'd say that the complete bike is genuine but the spare engine has definitely been altered. the raised cast in "No" before the XXE number is completely sanded off.

Thanks Ron , I was curious about the number on the engine

Dave

I asked him about the engine and this his reply.


Hello John,

As said in the description, it is 100% an original welbike XXE engine. Myself, Welbike uk, and a few other welbike owners all agreed that it is defo original. It also had the correct brass carb and air filter on before. My view, along with a couple others is in the description! It was in a little home made bike made from a welbike that was made in the 50s.

Kind regards
A

The number font looks correct, but I wonder why the raised "No" prefix has been sanded off. All the Junior Deluxe engines had it....It spoils it.

Here's my engine. Ron
