NZR Chopper couplers BP6040 (Kadee fit)

This is the coupler pattern for new couplers from around 1900-1936, though it could be found on stock much later than that. Half the heads have a cast in draw pin and cast pins are provided to be fitted to the hook. Generally the cast pins are a press fit which makes life easy. Can be used with out steel hooks (for magnetic uncoupling). Also available with a plain boss. Later, post-1936, couplers also available. (Plain boss illustrated)
