R180 Identification

The answer was simple (35 divided by 8 = 4.375) Ring - 35 and Pinion - 8 It will serve as the back-up to the R180 Giken 4:38.

Thanks for your suggestions and inputs. I was hoping for something really rare but another 4:38 (not in a "K" case) is great.

Been brain dead for the past few days after working on a new project.
