Do you have a definitive list of the exams you had to pass before "moving on" from ITW?.
Also, if anyone has a definitive list of the subjects taught at 4 SoTT that would also help with our research.
Finally, and this is a real challenge ... does anyone happen to have an original RAF Railway Warranty circa 1943 / 1944 .... a tall order I know .... but ..... fingers crossed!
In fact ... any original documenation from that era would be extremely useful.
