Yes there's always a catch, sorry for being slightly misleading, you have to have access to a computer.
Elliott Deutsch, a friend in the Coast Defense Study Group (CDSG) circulated an email from Bolling Smith with the following info:
"Just stumbled on this site. It has lots of downloadable files such as alphabetical and numerical listings of APOS, lists of publications for training, several camo manuals, ammunition, etc."
This site is a virtual gold mine of about 159 WWII (and some a bit later FM's, TM's, lists of APO's etc.,). I noted with pleasure a considerable number of manuals on weapons, artillery, fortifications, etc. among the titles.
