I know it was built by the Reading shops, they built these for the RDG, LV, and CNJ. Would anyone know the CR or previous number?

My guess is that's the same as SIRT #4 from back in the 70-80's.

My notes say former RDG but that could be a guess.

Surpising it wasn't from B&O (SIRT was a B&O division).

I think these cabooses were known as Northeastern cabooses,there was an two issue article about these cars in Railroad Model Craftsman "R M C" back in the 1980's...
