You will have to do the research. I've only checked the models that are relevant to my railroad/region/era. For example, I know the riveted mechanical reefer is correct because it is a Fruit Growers Express prototype and New Haven was a founding member for FGE.
Check the models against mechanical drawings for the prototype, most of which can be found in the MR and RMC archives. It takes some effort but not a super-human effort. Or, search the Railwire and Atlas archives, as this isn't the first time this topic has been discussed.
