mystic meg:
The booklet title is "Story of a Lanc (NX611)" by Goulding B and others, first published in 1974, 32 pages card covers. Looks as though it does not have an ISBN.
Available in the secondhand market.
Written by Brian Goulding, Mike Garbett and Sqn Ldr John Partridge RAF. No ISBN reference,
but the latest(?) copy was produced by Melton Printers of Lincoln In 1991. Somewhere I also have an original copy (1974) that was available by mail order from one of the UK papers.
To quote from the inside back cover of the 1991 booklet:
Whilst it would (or should the word be WILL) cost a hefty sum, well into six figures, to get NX611 up and running again, this remains the underlying hope of all concerned.
