Anyone aware of OOBs for the civil wars of 193AD and following?
The following seem to be reasonable starting-points for which legions were around and where:

One will need to do one's own fine-tuning, though: Albinus had the legions of Britain, Severus those in Moesia, Pannonia and Illyria and Niger those he could shake loose from the eastern contingents (including one of the legions in Egypt - III Cyrenaica). Didius had the Praetorian Guards but apparently not much else.
Herodian provides a narrative for events of the period, but not much OB information. He does mention that the local eastern rulers, far from giving Niger any difficulties, offered him assistance.

Our other main source is the Historiae Augustae http://www.livius.org/hi-hn/ha/hist_aug.html (http://www.livius.org/hi-hn/ha/hist_aug.html) (note: links to Lacus Curtius which is intermittently inaccessible)
[Edit] Check the links for the following contenders, as these have occasional OB info:

Auxiliary forces are harder to pin down, and I lack the pins.
