I am trying to get some information on a P-51 mustang called "Spare
Parts".
My wifes grandfather worked on this plane while he was in WWII. Said it
was
his favorite airplane. He was a mechanic and help build this plane from
three that were damaged. I am an amature artist and would like to make
a
drawing of the plane for him. Any information about this airplane or
flights would be helpful in putting together a historically accurate
sketch.

thanks in advance for the help.

Apparently P-51B, serial 43-6623, of the 310th Ferrying Squadron,
based in BAD2, Warton, was dropped in the water when being
unloaded from the ship at the dock in Liverpool:

It may have been eventually ditched at sea after repairs were
made from having originally crashed at takeoff...
