Hello, I am new to this site. I purchased a McClellan saddle, with saddle bags, etc. and several other tack from a friend's family member who collected civil war items and had passed away. I am now selling them because I am moving and need some advise. I listed the saddle and items on ebay. My question is I have what I originally thought was a leather girth but have since found out it is a carbine sling. It has US and TJ Shepard on the buckle. I will try and upload a picture. My question is how do you know if the items are original or reproductions. You can see the saddle on ebay. It is listed as a civil war McClellan saddle-fully loaded. Any thoughts? The horsehair girth I have listed says Rock Island Arsenal on it. Thanks so much!
