Thanks Stig.
Of the 6 lost on 12th / 13th , 5 were brought down intact; but letters apparently not recorded...
B1250, B1251, C4824, B1207, B1268.
C4630 "J" I mentioned was captured 19/5/18 but after squadron markings were discontinued. Usually--but not always---the crosses were marked on a white background.
These are interesting notes on 62 Sqn. losses etc...
Nick
