Hey Doug, My copy of "Mare Nostrum" by Jack Green (1990) says three rifle companies and one machine gun company. I see notations from years ago saying 6 light MGs per rifle company (I wonder what kind of LMG?) and 6 medium MGs for the machine gun company. (Probably Schwarzlose M07/12s captured from the Austro-Hungarians). 800 men, about. I'm sure that more recent scholarship known by others will have uncovered much more information. Look forward to reading about it.
