2104 Exhaust Stacks (4) and Steam Generator Vents (early)

In stock

As with much of our Highliners F Unit tooling, we have pushed the limits of injection molding to the absolute limit.  The extremely thin wall thickness as we have done with these exhaust stacks and the previous sand filler hatches, is supposedly not achievable under mass production conditions without the use of very expensive "High Flow-Melt Index" materials.
