Personally I do think it is late 19th century. It is actually a very nice relic of the Indian Wars period. This Native American-used Powder Horn displays several drops of horsehair. This is an ORIGINAL ANTIQUE centenary Native American-used Powder Horn, NO COPY!
At a value ranging from 600 to 800 Euros (about 700 to 950 USD). I think it is worth even more. I SELL IT WITH VERY LOW RESERVE.
