I used to travel, installing the modern exhaust ventilation systems you see hanging in Govt garages, mostly F.D.s.. (the black/yellow tubes from the ceiling). My favorite part of the job was visiting the hundreds of well restored and/or maintained antique equipment. Twice, a pre 50s engine was put into action in rural areas. One was an REO ...it needed to stop every few miles to have the exposed valve train oiled by hand
I miss doing that job. Has anyone modeled Plymovent or similar inside a station?
