Serial number 'X' suffix

[richard.feltham]

I've got a 1949 Mk I that has an 'X' as the last character of the serial number. Does anyone know if this signifies anything special? I can't see anything else that isn't standard on it.

I'd be very grateful for any information.
Many thanks
Richard

As i know X means a works exchange for a broken frame or engine.

Thanks for that Markus. that would make sense as some of the frame elements are earlier than 1949.
Cheers
