18th century, just over 2 ¼” length. Made from a heavy reed or hollowed stick with delicate angled lip for pouring into the gun barrel, inset base plug and shaped base with suspension hole. Wonderful untouched glossy age patina. The vast majority of these are made of cow horn. This example was evidently made by someone without access to cows as is quite understandable in a rural situation. Only such example we have encountered.
