Excellent work, Phil.
I recently found this deciphered Luftwaffe message from July 1940 which may be of interest (National Archives file HW5/3; report CX/JQ/121, Teleprint 22/para. 12):
On 8/7, 2 Ju 88 of III./LG 1 raided ENGLAND. It was reported to Fliegerkorps 4 that they started at 1110 and returned at 1410-35. One a/c dropped 8 250 kg bombs on landing-ground at YEOVIL, but they fell short. The other a/c attacked harbour at ST. MAVETH (ST. MAWES?) opposite FALMOUTH, where 4 250 kg bombs were dropped, but effect was hidden by cloud. Slight AA fire at WEYMOUTH. (A)
The "(A)" is a British rating of reliability, i.e. they're highly confident of their interpretation; "(D)" was the lowest, where there was a lot of guesswork about the meaning.
