Hello Brian
You can see elements of 183 Sqn ORB using the preview links on TNA. The viewable element (on page 7 of http://discovery.nationalarchives.go...index=1&page=1 ) indicates they were up between 1500-1600hrs.
As you say no indications of Luftwaffe losses, however could this be a Blue on Blue encounter? I've had a look at the USAAF MACR reports 5207 and 5208 which are for 2nd Lt Gordon Perry O-812478 and 1st Lt James Lynch O-804009 respectively. Both were flying P-51B Mustangs, with Perry acting as wingman to Lynch and had been engaged on a bomber escort mission to Berlin, interestingly both are reported as being lost at 1517hrs five mile south of the Isle of Wight. Perhaps Brian Cull who is doing a series of books on such encounters might have something in his notes?
In the MACR reports there is a weather report from Thorney Island giving conditions at 1500 BST as being "3 miles visibility in haze. 1/10 cumulus at 2500 feet and 2/10 high cloud above 9000 feet. Wind south at 6MPH".
Regards
Pierre
