When I finish my #71, I'll start on these three. I did a lot of the #75 and 76 a while back and they got shelved for other projects but injectors and domes were done. The 74 is a Balboa. I also have it in RGS (Westside). The 75 is a Westside Models and the 76 is a PSC semi kit. Was going to replace the C&S 74 with a Westside but already had a Balboa sitting there.
The #71 is a Key. It is getting closer. So far: Changed the undersized bell, whistle and air pump, Jacket panel in front of fireman door with washout plug, roof hatches, opened cab door on engineer side, Plow with cut levers, air tanks under cab along with other details on both sides under the cab. Replumbed boiler top tanks, piping from cab on eng side and pipe in front of FM door. Corrected FM side of boiler top tanks.
The tender has had the klinker rod rack built above the new coal "pallet", retainer with piping, tank stays, valves on rear tank, klinker rod on FM side and water leg valves with shields.
Still needs plow chains, glass, curtains and crew along with another once over to see what I've missed. Then weathering.
