The Boston and Maine Caboose No. 6017-100 production spanned eight years and encompassed three different body types: Dies 1A, 3C and 4. The main difference was that this caboose came both with and without ladder slots. The BLUE painted body is held to the chassis with end tabs.
Produced in 1959, 1962, and in 1965 and 1966, the "B & M" stylized logo and lettering is heat-stamped in WHITE on the sides. The blackened chassis is sheet metal that came equipped with AAR trucks that usually had one operating disc coupler. Cataloged as No. 6017-100, only the number 6017 appears on this caboose.
There are four variations:
Variation A: Was an early production example (Die 1A) that was a VIOLET BLUE color and is rare.
Variation B: Is MEDIUM BLUE with a high gloss finish.
Variation C: Is MEDIUM BLUE with a semi-gloss finish.
Variation D: Is a LIGHT BLUE color with a semi-gloss finish.
