MNG gifted B&SR 50 to us last year. We subsequently traded it to ML&M for B&SR flat 34. ML&M already owns and has restored B&SR box 51. 50 and 51 were both built by the B&SR in the 1880s; its fitting they are together. We were considering building a flatcar from 50's parts so this seems a more well rounded solution, from a preservation standpoint.
See ya
