16th/5th Lancers Officer's Collar Badges

A (non-matching?) pair of silver/silver-plated collar badges for an officer of The 16th/5th (Royal Irish) Lancers, each with two lug fastenings (north and south). As Churchill & Westlake 18.

Note: I think I have identified these collars correctly, although other units used similar collars.
