I agree with you Ross, that the ORs are a wonderful tool, but the poster was asking if there was a way to find out if a specific regiment had scabbards with a certain amount of rivets, issued frocks or fatigue blouses. AARs and orders and reports are rampant, but there is very little unit specific information in the ORs. (Now I am not blessed with the CD... I have the whole gazillion volume hard bound set)
As to the asked question, I doubt that anybody outside the board the decided to change things up really cared whether they had a seven rivet bayonet scabbard or a sewn scabbard, etc. etc. I am sure they knew a dress coat from a fatigue blouse, but the specifics and "types" we catch on to as reenactors and collectors I dont think mattered a whit to them. What the original poster may be looking for may be difficult to find. I know that on the fall 1862 and Spring 1863 muster reports for our unit, all that is noted about uniforms and arms is condition: "Good"
