PTR, thank you.
I already found the picture on the IWM website. Had to "remove" the trolley.
Now, if I think really hard I might remember the Jez type, 24953?
Plenty of A-size imagery on line but none for the tastefully painted British buoy.
Presumably the 1c was painted Orange as an aid to the Shack to get a good on top (wonderful position in nose or tail). Come the Nimrod I guess someone thought it a good idea to paint the A-size in dayglo as well to help the submarine see them
