On the horn itself I have rubbed a coat of linseed oil on it. Someone had asked about the diameter of the spout hole.
It is slightly less than 3/8th of an inch. I would be happy to put a coat of linseed oil on the wood and also add a staple to the plug end if you want. The horn has an inner base plug of 1/2 inch pine and a piece of walnut as the top base and stopper. Pins around the horn are brass.I was asked on another horn to add some extra detailing so I tried to do some engrailing and divided the top part into half round and half 8 sided. A man had asked me about a priming horn.
If interested I did find one I could possibly copy. If interested please contact me and I;ll send a photo. This item is in the category "Sporting Goods\Hunting\Vintage Hunting\Black Powder". The seller is "marleytigerbobo" and is located in this country: US.This item can be shipped to United States.
