hello All ! i would like to be schooled on factory cast iron pistons. here we have pistons with 2 rings and pistons with 3 rings. are these differences between years (earlier vs. later) or differences between models. i can tell you the pistons attached to rods are the pistons that came with my lower end, 27 JD13514. i do not know what model of twin or J-type model the other set of pistons were associated with.... why would the one set have no 3rd ring (oil control?) and the other piston set has what i assume is an oil control ring?

also, what diameter rod was used for 1914 fender braces?
Thanks in advance!
