Re Mr. Ford,
Your posts were not visible when I posted my reply concerning Shores' books. I'm guessing they were delayed while the mods reviewed as your are on probationary status.
Indeed, your book is one of my primary sources and what led me to find out more about the RAF's contribution.
USAF History Office asked me to write 25,000 words booklet on AVG and I thought the RAF contributions would make an interesting sidebar.
