SATCO'S WHIPPING BOY (#3345),
Thank you for the thumbnails - No.5 of the first group gives a good look at the prop. It is clear that is in the (correct) "Fine" pitch position. (Google <Two-speed propellers> "Diagram of controllable two-speed pitch mechanism").
Many Pages ago I have Posted my doubts (based on less clear pics) on this point. I now fully recant !
(I was in ATC at Linton Sept/'62 - Summer/'64 - you do not give your age.......?????)
