Purposed for LOMO OKC1-200-1 lens (2.8/200mm).

This gear is for APERTURE ring. One issue is that OKC1-200-1 lens extends 26.5mm forward when focusing from infinity to minimum focus distance. The gear is only 14mm long, so it will de-couple from drive FF gear at the middle of the range. We will make longer gear later.
