Nice horn. Love the Sibley’s work. And the 1774 date.
I like to put dates like 1773, 74, 75 on Rev War horns. I figure most prudent men would have recognized and interpreted the signs of the times leading up to that conflict. And they would have made or commissioned a horn - and had a gun and supplies at the ready, ahead of time. Whether to be prepared for actual war/militia service, or for protecting their family and property if fighting were to come here and happen close to home.
One I made for my son with a ‘75 date.
