I recently acquired some cool items used to make lanterns and Lamps by the Handlan Mfg Co. of St Louis. I believe this is a sand casting box used for the No. 2000 lanterns. Check out my other listings… Ive never seen any mold or manufacturing type items from this company before…. Really cool pieces, make sure to check out the other listings too! The Handlan-Buck Company of St. Louis was one of the premier suppliers of railroad lamps, lanterns, and other hardware. Tracing a corporate history back to 1856, the company was both highly respected and patronized by railroad companies, with its strongest markets being the Midwest and West. The company was particularly known for lighting devices that used combustible fuels like kerosene.
