I sent the fella a message asking about the Eagle being from around the early 1800's and this is the reply that I received...
Hello,..And thanks for that great question,...The Spread Winged Eagle goes back to a little before 1750,but was more prominent around the Rev. War,..and into the Civil War,..The Full Shield Crest is also later ,but the Striped Crest is seen in the mid 1700's,..The earliest Horn I have ever owned ,was dated 1725,and was American..Profile Eagle,...Thanks again,..John
