When I was deeply involved in HO, I did a lot of kitbashing. I took a BLI 2-8-2 and did a heavy mod adding an Elesco Feed Water Heater along with additional brass fitting and a new brass oil bunker to the tender. The model took first place in a contest.
I also kitbashed 2 Proto2000 2-10-2's, one with a Worthington FWH the other with an Elesco FWH.
I loved the sound these produced, and expect to see these running again on a club layout.
Here are some photos of the mod along with a video.
Hope you enjoy it.
