Don't believe you will find much in 3AD. The 3d AD went to Germany in 1956 from Ft Knox. I wanted to transfer and go with them, by my CO disapproved it. By 1956, the standard mediums were M-47 and 48s, the Pershings being replaced in Europe starting in 1953/54, as the M-47 became available. In Korea, the M-46 was the medium, the M-26 being replaced by the M-46 (new or retrofitted by Tokyo Ord Depot) until summer 1958 when they were replaced by M-47s.
