Can anyone tell me (or tell me where to find) the serial for Wessex HC.2 “BO” that flew at Gutersloh in 1975. It’s the only registration I’m missing from all of the aircraft I have flown in/flew.

Any help greatly appreciated!

This thread is kind of an oldie but if you are still looking for the serial of “BO”: According to the list of Wessex used by 18Sqn at Gutersloh on http://www.sg-etuo.de it was XS674.
