I used to service both types. The "B2" was standard Japanese or German built, with Honeywell LTS101-750's turbines fitted. Later came an improvement to upgrade to CAT-A performance of LTS101-850 turbines. The "C1" model was only German built maybe, with Turbomeca Arriel 1E2 turbines fitted. This also required the 'VARTOMS' to be fitted. A few noticeable differences between the aircraft as well, configuration and interior/cockpit items.
