Hi All
http://www.naval-history.net/xDKCas1940-05MAY.htm has them as based at N Coates and lost in Air operations. The Sqn given is 812 but for some reason it is labelled as RAF which might reflect their duties at the time. Scroll to 24/5/40 and there is also an 825 Sqn loss on the same day but with different names
Regards
Dick
