These are wood bases destined for our Commercial / Collector engines. We cut and hand finish these here too. Since the rich wood tone we use is not available commerically, we mix our own special formula to get the color just like it needs to be. After a couple of days for the stain to dry, these boards will be fine finished and immediately used in one of our model 55, model 20 steam engines or 95G Turbine engines. We also cut and finish the wood bases used in our 85G, 70G and 25G hobby engines.
