David was good to have a look at your site “wallyswar” Coincidentally my father was also Walter, and likewise referred to as Wally!
You have obviously put a lot more work and effort into your research than I have – well done, it makes interesting reading. How I wish I had my fathers log book it would make things considerably easier for me. Also wish I had shown more interest in all this whilst he was still alive.
All the best Ross.
