Well, the whole canopy is different. The bubble top on the KR200 was simplified over that of the KR175 by the use of a larger curved glass windshield that formed A-pillars with the side window frames. This allowed the bubble to be simpler and more compact than the KR175 bubble, and it was consequently easier and less expensive to produce. The windshield wiper, manual on the KR175, was electric on the KR200.
Basically, it looks like this car has the canopy of the KR200 and was probably built late in the run. Maybe one of the last KR175s
