Well for one thing the PRR offset side is a foob. The PRR had only one offset side hopper and it was a Clas H27 eleven rib 6 bay 90ton hopper built in 1930. # was 220300. The rest of the vast PRR coal hoppers were ribside. The reason was that coal was acidic and when wet would corrode the exposed welds on offset hoppers but rib side hoppers had the welds on the outside of the car where they did not come in contact with the coal. Concor is doing three numbers and the car is black. I thought prewar Pennsy hoppers were red.
Also regarding the couplers "rigid jaw" would imply non operating but notice the shank. It has the same shank end as the McHenry, Accumate and the MT 1015. Unless the new Bachmann operating coupler is different this may be the death knell for the "T" shank coupler.
