A Pair of chest hinges with protective leather straps intact(quiteuncommon).....since my passion is colonial antiquities(35yrs)....i can say this much about them.....i'm giving them a 75 year window....could be before 1750 but not after 1825......i dont think u'll find much argument there.....photos are very detailed,showing specific wear points critical to authentication.the real american McCoy...thanks for consideration.
