FWIW i recently saw an ebay ad for reproduction mounts for the P14 (T) (Rifle no. 3 mk1 (T) ). It consisted of a set of the bases plus two sets of rings - 1 in 7/8" Dia and 1 in 1" diameter. They were expensive but if the organizers are going to permit Weaver K4's on Gew. 98's then in fairness there should be a similar exception for for the P14 (T).
