There was a Sunderland that had been turned into a faux Sandringham as it wasn't done by Shorts that was flying at several shows back in the 90's but seems to have disappeared. I am not sure where it went. I knew there was one at Hendon. I didn't know about the one at Duxford must have missed that one. I will have to toddle along and have a good decko. Always good to go there as one of my favourites is there as well in the shape of TSR2.
Thanks for the help guys.
