I think they also made a PRR N5c in brass. The cars are scale size but like most all of the Williams brass they lack detail.
Actually Williams made the N5b Cabin car not the N5c. The N5b has rectangular Windows and rectangular cupola. the N5c looks more streamlined with the Circular porthole windows and angled cupola.
