Hi Sally-Ann Thanks for that additional information, might prove useful in finally identifying the type of bike. I haven't contacted the DVLA, I'm not sure that they can supply such information (or more probably won't). I suspect the information is also available from the IWCC (the licensing authority), but again maybe it's not made public. Chris - thanks for the link to the Invicta, I'll keep that in mind.

It must be a very early model based on these markers/features Have you thought of checking with the DVLA for the number?

You can see the picture at http://www.vectisjon.com/baker.htm. It seems like a really useful database that no-one has been able to tap into as yet (AFAIK). snip
