Steam & Excursion > Westinghouse 6SL brake valve

Folks,
     The former Weyerhauser BLW DS4-4-750  #101 recently moved to Train Mountain in Chiloquin, Or is missing some small parts and need to find replacements.
     Near as I can tell, the brakestand on the locomotive is a Westinghouse 6SL. We need to find both brake handles for this brake stand to furthur complete the cab.
     We would appreciate any leads where we may find these handles. Also need to find three windshield wiper arms. These had a clamp and set screw to attch the arm to the shaft on the air motor.
  Any leaads would be appreciated.
