This muffler was a “found” Big Object we ran across on our way out of Vandalia, IN. It’s on US-40 west of town near Exit 61 on I-70. We stopped in Vandalia to see the historic marker designating the terminus of the “National Road.” The National Road ran from Cumberland, MD and was planned to continue to St. Louis, however funding ran out in 1838 when the road reached Vandalia. The National Road was the first major road to use the new macadam road surface. The interesting things you know when married to an historian.
