1-1/2 inch scale live steam blow down valve sand patterns and lost wax handle mold. The sand patterns are from the original Railroad Supply Corporation, Burbank, California, that went out of business and sold many of the assets back in the 1990's. Includes 3 sand pattern boards that make the blow down valve or 3-way valve body. All of these patterns were used to make the blow downs that are listed in the Railroad Supply Catalog #9 on page E-4. Includes the two original master shop drawings that were used to machine either the right or left side blow down valves or the 3-way valve. Listed on eBay February 2016.
