Available in 4 sizes (rebore oversizes):
This is a piston ring set for the T90 and 3TA models, machined to a +.020 oversize for a rebore. The CP prefix marks it as a Hepolite-type ring set rather than an Amal carburetor part, and it's meant to go with a piston that's already been taken up to that same +.020 dimension.
