Pair of VTG Iroquois china dinner plates US Army Med. Corps

This listing is for 2 plates, the picture shows one. Pair of Iroquois china 1951 dinner plates. US Army Medical Corps logo is on the front. Marked on the bottom P.R C-2 1951. Plates are 9". I made close up of the plate, there are imprints like a scuff in the same spot on every dish. I dont know if thats from manufacturing, or storing back then. I have 10 of these plates and they all have those marks on the backside. These are in good condition. Each weighs over a pound.
