The steam locomotives of the Nevada Northern use A 50 brakeshoes. We are almost out of brakeshoes and need some more. My first question is, does anyone know of a source for A 50 brakeshoes? We need both lefts and rights. If that doesn't work, the NN Ry will then develop the patterns to cast new ones. Are there any organizations out there that need A 50 brakeshoes and would be interested in partnering with us to produce new ones?Thanks,Mark BassettNN Ry
