This is a topic that comes up every now and then. "Loco112" on several forums has been gathering drawings and prototypes to produce a 1/2 size coupler, perhaps he will be going into production? A fellow in the Philadelphia area was looking for couplers for his small mining locomotive and cars, though I do not know if he had any success. The only massive collections of 1/2 size Sharon couplers that I know of, are at the Billy Jones Wildcat Railroad and at the Swanton Pacific Railroad Society. Both of these are decendants of the Overfair Railway of the very early 20th Century fair in San Francisco. I am hoping a source for these couplers is identified and shared on this thread, as I would like to purchase some myself.
