Thanks to everyone who has responded to emails and given me information.

A special thanks to my big brother who worked out all the PERL scripts for the serial number search, Lambretta gearing calculator, and the Vespa gearing calculator - couldn't have done it without you!

Thanks to Joe and Marylin (the neighbors with all the tools and time)....and sandwiches.

Thanks to my Mum for periodically letting me make her garage smell like eurethane paint for days.

Thanks for Sierra for letting me play with my toys.

Thanks to Rhian for billions of cups of tea.
