Hi there...new to this forum and have a question about a driving harness. I have a little experience driving but would like to know what to call this set of equipment. I am helping out a friend who owns a used tack store. She came into some driving equipment and has no idea what its value might be, what to call it....etc. I know some basics...there is no breast collar, no hames, just the surcingle/girth, reins, and crupper. How can we tell what its quality is, and what to re-sell it for? Thanks in advance!!
