Hi Jason,
You are correct. The #3126 is the one that was on Ebay. It is in good condition but it does need two Sharon knuckles and a brake shoe. It is lettered T.T.C &P.
The other Three cars did come from the D&S. The two boxcars are lettered for the D&S while the Flat car is still lettered for the D.&.R.G.W.
The rest of the P.C. roster includes four Retlaw one Disneyland coaches Numbers 102, 103, 104, and 105.
We also have the Cuscatlan private car Two ex Crown Zellerbauk Flats and two former Apache Powder flats.
