I've been planning a couple of cohorts of EIR Praetorians, for a year or so, but I've not been able to find suitable signifers wth the very tall and distinctive Praetorian standards.
Praetorian standards were taller than regular cohort standards, and much more highly decorated, with wreaths, images of the Imperial family, plaques and so forth. They were so heavy that, during one long march, the signifers were given permission to load their standards onto carts.
The closest I've come to suitable figures are these A&A Praetorian signifers. The figures are OKish; I don't like the later-period leggings or sleeves, but I may be able to conceal the former with greaves. I've removed the original tops of the standards, and lenthened them to the maximum height that will fit in my storage boxes. I've added a plaque to each, with a (rather crude) scorpion on it. They'll do!
I have a little more conversion work to do on some other figures, and then both cohorts will be off to Nick for painting.
