I got the build info from GM Canada on my truck a few years ago and included was the paint and trim codes. My truck is a '53 1/2T which of course is a model 1314. There were 2,424 units built for 1953 model year and the paint code is 338-Sahara Beige (Dulux paint code is DU-143). Trim code is 394 - Brown Leatherette, hope this helps.
