Thanks Ed, some interesting ones there.
#2 looks like Battle K7696/QT-I of 142 Sqn, lost on 19 May 1940. All three crew POW. Most photos show it considerably later, with more bits missing.
Has anyone ever seen a photo where the code and serial are both clealry visible, as I like to keep a note of such things. There are some photos at:

which are almost good enough....
#4 N3200 is now of course flying as G-CFGJ (or rather an aircraft with a few bits from this one is now flying)
#6 is I think actually white 39. I'm not sure it has ever been identfied - anyone?
