Troops:
That's a Jewish prayer book. It reads right to left and our normal back cover is the front cover. Most Jewish fought for the country where they lived (except Germany ). Notable among them is Robert Tuck. Here is an excerpt rom the Jewish Virtual Library re "Jewish Pilots & Ground Crew in the Battle of Great Britain:"
Robert Roland Stanford Tuck was known as “Lucky Tuck” [39] and was Flt. Lt/Wing Commander with 92 and 257 Squadrons. He was born in Catford on 1.7.16, son of Capt. Stanley Lewis Tuck (Capt. in Royal West Surreys, in WW1 ) and Ethel Clara , and educated at St Dunstan’s College, Reading. He was at sea for two years as a Cadet and then joined the RAF in 1935. Whilst training at Grantham, he was almost killed in a mid air collision caused by turbulence [40] and he had to bale out severely scarring his face. At Duxford in 1938 he became one of the RAF’s first Spitfire qualified pilots.
...Tuck is probably the most highly decorated Jewish WW2 pilot after Louis Aarons, VC, DFM. He is credited with 30 kills - one not added till 1982 [46] making him the eighth ranking ace of the RAF with more victories than any other British pilot [47]. His portrait hangs at Bentley Priory RAF base at Stanmore – Fighter Command HQ in WW2 - alongside many other Battle of Britain pilots. He died aged 70 years on 5.5.87. His Jewish Chaplain card mentions an article on him in the JC in Jan. 1941. He was also a great friend of Jewish Fighter Pilot Ronnie Austin Jarvis (killed in 1941) and their visit to the home, for example, of the Jewish Barnato family is well documented [48].
A more detailed book ia available at Amzon.com...A Question of Honor. It is the story of Kosciuszko Squadron.
The figure could might as well represent Robert Tuck.
By the way, I have a Jewish prayer book that looks just like it
