The china pattern used on the GB&W business car ROAMER.

The Green Bay Route replaced their ancient business cars #99 and #500 in the early 1940s with refurbished caboose #603 and car #600 ROAMER. Car #600 was built by the American Car & Foundry Company in 1918 for the astronomical price of $200,00 for oil millionaire Joshua Cosden.. By 1944 the car was reduced to serving as housing on the Morris Run Coal Company before being purchased by the railroad.

The GB&W returned the car to its previous splendor, spending $33,000 on its restoration. The is multicolored china with flowers of blue, pink, and yellow  used on the car was known as "Rose Marie" (or more popularly as "Roamer"). It was made by Syracuse China.  The back stamp on this pattern puts its date of manufacture sometime between 1927 and 1950; more likely towards the latter part of this range based on the 1944 purchase date for the railroad car.

ROAMER remained with the Green Bay Route until 1971, when it was sold to a private owner in Ottawa IL.

I have never found out if the use of this pattern was limited to just the GB&W's "Roamer" car or not. If anyone can provide information on this, I would appreciate a message at mark@mathu.com.
