The Glasgow Yeomanry was one of the oldest Scottish yeomanry units, troops originally being raised in the Glasgow area from 1797. This example may date from as early as 1848 and would have been unchanged until 1902, when the king's crown replaced the queen's.

This belt buckle would have been worn by an officer with the dress uniform up to WW1. To my knowledge, it is the only belt buckle which displays a mounted figure, with the exception of the St Martin's Volunteers of the Westminster Rifles from a slightly earlier era (the 1860s).
