|GBW 20 combination RPO/baggage, ex GBW 53 or 54 Coach, in front of the former C&NW Marion depot at the Marion Area Historical Society at Marion, WI on 9 Jul. '14. There were no obvious markings other than faint stencils on the trucks that included, "LUB PAD, NOR 6-6-66, GBW". It used to be displayed at Rapid River, MI; it was moved from there to Marion, WI on 2 Jul. ’13. According to http://greenbayroute.com/, GBW 20 was originally GBW 53 or 54, a 60'-0" coach built by Hicks Locomotive and Car Works in 1908; rebuilt as an RPO/baggage car in 1929-30. Sister GBW 21, ex-GBW 52, is on display at National Railroad Museum at Ashwaubenon, WI. GB&W donated sister GBW 22, ex-GBW 51, to the Wisconsin Historical Society in 1970 for display at Stonefield Village in Cassville, WI. I'm not sure if it is still there, it is not mentioned with the other RR equipment on their website.
