Capped Locomotive Smokestack

This is an HO scale locomotive smokestack, 45 scale inches tall and 16 scale inches in diameter.  Designed for an HOn3 United Verde and Pacific #5 2-6-0 that I am building, but could be useful for many other locomotives.   I am making this available in detail plastic and brass, and also processed versatile plastic.  Brass will add weight to the locomotive for not much more cost.  Versatile plastic is a little cheaper, but also stronger than detail plastic - the drawback is that it is not as smooth.
