Gentlemen, many thanks for your replies. Thats the great thing about Pprune, there is always someone who knows the answer or where to find it.
11Fan. That is an incredible photo and thanks also for the APCF web-site. Looks like another excellent way to pass a rainy day.
Willitrun. Just what I was looking for!! Like BSD my greatest aviation wish was to have flown one of the big piston-engined aircraft. I was rotary, Sikorsky S61 and the Civil Chinook.
Just one more question. Did the DC6/7's have variable oil cooler shutters? I can't see any evidence in the photo's on Airliners Net.
Again, my thanks
