The Ps-4 pictured above looks very much like my 1990 Williams brass Ps-4 which has very little piping on the boiler or smokebox. Prototypes vary---Pegram Shops covered some of their Ps-4 sand dome piping with a shroud. I can't make out the road number on Bob2's engine---mine carries 1401.
A rust red tender deck was prototypical on both Southern passenger and freight engines according to a long ago article in SRHA's TIES Magazine.
