I've been trying to unpack an engine here and there and take some photos of them lately. These two are scratchbuilt on PFM USRA light 2-8-2 frames and drivers. Boilers, cabs, cylinders and in the case of the 4101 the tender is scratchbuilt. 4151, one of three 4100s equipped with a Coffin FWH has an altered PFM 1500 tender.
