Scott,
as far I know, three pieces on/about LFT/SFW "aces" or victories are available:
a) M OīConnorīs book - ISBN 0-912173-03-3, with a chapter on FH (pp 176-181),
b) C Chant - an Osprey book; app 100 pages, ISNB 1841763764
not so many details on FH,
c) K Meindl 8 volume series on A/H victories, listed by date and by fronts - Russian (2), Romanian, and Italian (5) - in German.
It is probably the best source on the topic, but with no particular summary on FH. Havenīt made an index so far...
The link below gives a flavour on the stuff:
Sonderdrucke
J C Steiner published a list of pilots, who received a "Feld pilot" badge. The list of pilots with a diploma from A/H Aero-Club is availble as well.
J C Steiner also published a book - Heldenwerk 1914_1918 with two pages on FH - in German.
Hope will have an opportunity to scan those two pages for you soon...
In any case let me know what info you need.
Even though I am interested predominatly in WWI plus a couple years later, could you be more specific on the album - pagination, nos of snaps.
I guess you got a real treasure!
