Chuck, the .024 rings could be any brand for any aftermarket piston. Lots of earlier pistons used the .024, thanks to Mac introducing them on the Mc6 and late Mc10's in '60/'61. The .030 may well be factory West Bend. A lot of factory 610's, even Libberton/Chrysler used .030. If you can check bore, the Mac will be 2.125, 2.165 or 2.280. There were other Mac bores, too in the engines between Mc70 and 101. West Bend 610 and Homelite KL100 were 2.1875. West Bend 820 was 2.531. PP-58 2.094. There are more I have to rack the mind to remember. Tom S. probably remembers. There were thin ring pistons also for Clinton, PP-81/82 and the 580/700 Benders from Wiseco, Palmini, and many more. Almost everybody used .024 rings. TJ
