Williams, White & Co. of Moline, Ill were manufactures of the patented Burnett & Clifton Automatic Coal Chute for Coaling Locomotives.  Among the many customers was the AT&SF, which had these chutes located at La Junta, Colorado, and other places along their mainline.  Another customer was the D&RG with a 24 pocket version at Gunnison, Colorado, and a similar structure in Salida serving both standard and narrow gauge locomotives.  The Rio Grande Southern in southwestern Colorado had three such structures, located at Ute Junction, Rico, and Vance Junction. 
 
This kit represents the structure that was (and still is) located at Vance Junction.
