Don't have any from WWI, but I do have a couple of Old Glory Victorian ones you can have. Don't worry about the weapon parts, they're not on the models, but the saddles are. Those reins that the chap is pulling on are moulded as part of the model, but would be easily removable if you don't want them. They're unpainted, this is a picture from the OG website just to give you an idea:

Close enough? If so PM me your address and I'll pop 'em in a jiffy bag for you.
