Just to carry this thread a little farther...It might be a good idea to identify a group of uniform, equipment and weapons (for want of a better word) "experts", so that those in need of info might know who to ask beforehand.
I know zip about the ACW, Revolutionary War, etc., etc., but I know a bit about the Great War and would be willing to help out in that area. And have done so in the past, hopefully not misleading too much. So far I have an image and text database of about 1.5 Gb all devoted to the First War & cross-indexed by uniforms, equipment, weapons, nation, illustrations, photos, etc. And I'm adding to it all the time.
Just a suggestion,
All the best,
Dan
