MATT, No, oddly enough, all it says is "FRONT END PAINT" I assume this to indicate whatever the shops were using at this time-probably a mix of linseed oil and graphite. I remember painting smokeboxes with liseed oil and graphite on a hot engine at North Freedom, Wis. some time ago. you paint it on and then rub it down, leaves a nice semi-gloss metallic look on the box. Smokes alot whie you're putting it on though. I recall reading an interview with a C B & Q loco painter who said their small pacifics on local passenger runs would get new front end paint every second run or so. The foreman would come around and say Jack, give so and so engine a necktie; meaning, pilot and smokebox. Today, railroads dont even wash em!
