Oops. it is a G Mark 1.0 cc, 0.61 cubic inches.
They also make a 1.22 CI twin which would be perfect but is hard to find.
I believe the designer flew it on the G Mark 0.61.
Great covering job BTW. Compliments.

Thanks. To tell you the truth I'm happy with the performance of the .049 on it. This one is a keeper
