Hi folks,
Any info., other than the obvious, would be greatly appreciated.
Tried googling and the only other copy I could find was from a University in Finland.
It's printed by Blackie and Son Limited and dated 1920
This also appears to have been in some kind of R.A.F. library at some point as there are two stamped dates of 1926 and 1937
Cheers in advance, Jason
