Hi there,
I believe that G.A.J.Morrison's N.C.O.service number,1345719,shows that he enlisted in Edinburgh,sometime after February 1941,although I am no expert in this area.I do have some more information about the operational career of F/O.Pope and crew before joining 156 Squadron-a period with 300 Squadron from July 1944 to September 1944 and a brief period,six days,on 100 Squadron.
Hope this is of help,
Regards,Mark Simpson.
