I am in the process of building a chemical plant on my layout. Name will be Diamond Chemicals because I have 20 tank cars (Micro-Trains, Intermountain, Atlas) lettered for either Diamond Chemicals or Diamond Shamrock. All 20 cars have an identical logo. I would like some signage on the chemical plant that bears this logo. I've searched the internet with no success finding this logo. Don't know if was a real logo, altho it seems so because the above three manufacturers used it. Anyone have an idea where I might find a picture of the logo that I can use on my signage?
