British leather neckstock with buckle clasp

Blackened leather British regulation neckstock for private soldiers. Used from 1802 up to the Crimean War with minor modifications, it was a virtual instrument of torture, designed to enforce the correct military uprigth posture or "bearing", with the head well held up and facing straight to the front at parades, but was regularly worn on campaign and combat as well. It was fastened at the back of the neck with a brass clasp. 
Correctly replicated from an original specimen preserved in the regimental museum of the Royal Welsh and dated from 1837. Leather thickness 2-2,5 mm, height of the stock 85 mm, slightly reduced at the front to allow for the chin, and at the ends to accommodate the clasp prongs.
