Parlor Car Alamosa's conversion into Coach #350 was done at the Burnham Shops in the late fifties. As with all other "Silverton" equipment, 350 was fitted with seats from retired Denver Public School Buses.
Not only were the Parlor seats removed, but also the Galley and dining area. An additional vestibule door was added on the left side, and the blank windows in the galley area were fitted with windows. It is doubtful anything removed was spared from any of the cars, but I think I remember seeing one of the seats at the Colorado Railroad Museum several years ago.
