Marion Reeves in the USA and Ross Prince in Australia or maybe Jaap Rietveld in Belgium may have some parts but shipping a heavy starter would be very expensive. Let me know if you want their contact details.
And I yet have interest - want to ask advice from all on other question also. I create a museum in Russia "Allies" (in a museum it will be cars and motorcycles - technique the 1941-1945 USA, Great Britain - on which the Russian people militated against Hitler). Very important project. I can not find helpers in the west. Where to find a help? you will look the details of project - http://www.lomakovka.ru/allies-english.html
