New product from Steel Mill Modelers Supply!
Boiler House Forced Draft Duct. 6 piece kit including brass stack (HO). N-Scale uses Evergreen Tubing. Two styles of the top piece will be available. The one shown is for a 20 degree roof pitch, and the other will be for a flat wall. I’ll get these cleaned up and post some nicer photos.
Pricing will be announced on official release next week.
