Thanks for the post Larry. The Erie also rostered similar cars. According to the records of A.T. Kott Mr. Parri only built 5 Erie/Susquehanna flat bottom hoppers. Someone check me - but I recall Quality Craft or Ambroid (both manufactured by Bob Weaver) offered wood body, white metal detail kits for the same prototype. IMO your drawing a parallel between Fischer's passenger cars and Parri freight cars was spot on. I'd love to see a thread on Fischer cars. I spoke with Joe the month before he died to see where I was on his wait list - he said I was next. The car Joe was to have built was the modernized PRR heavyweight Pullman Keystone Banks - my favorite Pennsylvania passenger car.

I believe that was an Ambroid kit Ed.
I know a certain O scale brass importer in PA has one built up.
