Hello and welcome, nice pics and story about your car. I too have a Trojan which I brought back to life with a lot of help from friends, people here, and the Heinkel Trojan Club:
http://www.heinkel-trojan-club.co.uk/Join the club without delay, I am a member and my rebuild was helped hugely by parts, books and other help from
the club, which has two spares custodians and very fair prices. Also of supreme use is the club's Parts List book which will help you to identify everything you do have, and order everything you do not; I cannot stress too highly that this book is worth ten times its price!
Next make sure your car(s) is/are registered with RUM. The register exists to keep a record of it, if it is ever stolen it might be traceable/identifiable. If you ever sell the car notify the Register and ask the new owner to update the register's records, it is there to help all owners and costs nothing.
Hope this helps, good luck, and enjoy this forum!
