This came in today's mail, a 1938 dated Officer's Pattern 25 waist belt. Wasn't quite sure what it was when I bought it, I just knew it was different from my other belts. This belt has a different type of back buckle arrangement having D rings attached to the lower ends of the straps. Instead of the snap stud on the left side for the bayonet frog, this belt has a sword hanger. I wondered if it could be Officer's belt?
I sent photos of the belt to Karkeeweb.com and confirmed my suspicions. "Not just a variation, but the very first blue-grey pattern of webbing, intended for officers only, Web Equipment for Officers. It was announced by A.M.W.O. in 1926. We cover it here. R.A.F. W.E.O. "
