Well, if you have a unit in mind to join up with, most have a pattern they use as their particular uniform "issue". You could check with them & see if they have a loaner pattern for you to use. Aside from that, I don't know if there are any commercially available military patterns for Rev War out there. There are some F&I era patterns that are adaptable for either military or civilian, so there may be some for Rev War....haven't seen any myself, tho......
