Blimey mate we have defo got too much time on our hands!
I have Spenser Whiting claiming 2 on 15/7/44 and no mention of Ford.
The Ju52 is a bit of a mystery. In the accounts I have seen they only state they attacked it. No mention of what happened. Like you I have assumed they shot it down but neither Smith nor Rorvik have it listed in their totals. That leaves the two others in the flight, Vorster and Moore, to make the claims. This means possibly three victories with missing or partial claimants on that date!
Your other details match mine.
cheers,
Keith
