Trevor, some guys have already done (maybe not by 100%?) what you want to do, but there is always a possibility to find something new, isn't it. Visit this site:
http://www.preservedaxisaircraft.com/
and look for Fieseler Fi 103.
Another source could be the book of Peter W. Cohausz (in German) "Deutsche Flugzeuge bis 1945" - i have his address in Germany.
I'm sure the net is also a good place for research.
Have fun.
