I solved the history of this aircraft some months back which in due course was duly acknowledged but now find my response has been deleted from the readers responses colunm and am curious as to why. Just as a point of interest,thats me in the back seat in the photo (Camden 1971).
Unfortunately, there were a few repeats ... this was one of them. Ron did solve this one earlier.
