A little background... these long hair sporrans evolved by the 1840s and for the rest of the 19th century were the standard sporrans for civilian day dress, civilian evening dress, and military dress. They were by no means ever confined to pipers, or the army.

Some Sergeants of the 42nd Foot in 1865



and some civilians in the 19th century, pipers



and non-pipers





We think of them as being of horsehair, such as this example made in 1938



but the early ones were goathair



The horsehair sporrans, indeed, were actually horsehair added to a goathair body, as can be plainly seen here
