Brass Numeral '7' - Possibly Part of an early 7th Dragoon Guards Other Ranks Shoulder Title

A UK made brass shoulder title with an original single hexagonal fixing loop to the reverse. Circa 21mm tall and 15mm across. I have put this numeral above a separate early 'DG' title in the final photo for comparative purposes. The DG is listed elsewhere for sale (Item 67503 - now sold). They look like a correct match.
