An ad by the Standard Stoker Company in the June 18, 1937 Railway Age magazine features GB&W's class D-47 Mikados.

The text of the 8½" x 11" ad says:

GREEN BAY ROUTE

The Mikado Type (2-8-2) locomotives built
late in 1936 for the Green Bay & Western
Railroad represent highly efficient light
freight locomotives.

They have 64-inch driving wheels and
develop a tractive effort of 47,250 pounds.
The weight of the engine and tender loaded
is 456,300 pounds; the combined heating
surface is 3617 square feet and the grate
area is 60.4 square feet.

The power is fired by Standard Stokers.
