Careful, the Hutchins roofs used on boxcars was different than those of the FGE/WFE/BRE System in that the roof panels between the ribs did not have the corrugation pressed in as on the boxcar version. My theory is that the System purchased only the roof ribs but fabricated their own roof panels.
Also the Hutchins roof on the Westerfield ex-PRR R7 FGE reefers needs to have this rib removed. I alerted Al W. to this after I received my kits but I am not sure he changed his patterns. Also the roof was only rebuilt between the hatches with the original Pennsy hatches remaining in place. Dimensionally they are different than those found on otherĀ FGE/WFE/BRE cars.
