File:RRSC CouplerPocket Pattern.jpg

Railroad Supply Corporation original master duplication mold to make a 1-1/2 inch scale front coupler pocket from the old RRSC Burbank, see Catalog #9 on page E-10. Pour special liquid plastic into mold, let harden, and pop out of the mold to create a pattern that mounts to wood board. Put 10 to 12 of these on a board and that is how a sand pattern is made to produce castings at foundry. Listed on eBay February 2015.
