Hey Rogerson, if you look up Penny's of Ontario, Myles (Penny) has belt buckles to fit that belt. I bought one for Royal Artillery and re-fitted it with the Army ensignia from a Dress Blue belt buckle (goes outside the coat). The belt you have has not changed in size or design for the British Army, only in color. I got mine in Iraq from a squaddie I met since I forgot to get my kilt belt sent over. I piped kilted there a couple times on the holidays. It looks like we enlisted about the same time if you are at 20 years. Cheers
