I bought number of Thiokol publicity/advertising brochures on ebay a while ago. There are a lot of interesting photos including the one above that shows Harold W. Richey posing with the "milestone" Hermes rocket motor which was fired in December of 1951. In that firing the motor fired for 41.2 seconds and produced 17,172 lbs of thrust. Fourteen months later it went on to successfully power the RV-A-10 rocket from Cape Canaveral. The Hermes is credited with validating the concept of large solid fuel motors. There is also a series of photos that show the process of prepping and loading the shuttle SRM's that I'll post later.
