Hoping some one can help on this-the museum has been given a dinghy, RAF triangular about 7ft each side. Marked as follows
c2176 (preumably serial no)
DRCo (presumably Dunlop Rubber Co)
MID30
A.I.D.T.A.6
Jul 1940 (preumably manufacture date)
it was apparently recovered in the North Atlantic "late in the war". Any one put a type to it ,no of persons , type of aircraft? thanks Pete
