Here is a pic of three versions of the MAX-III .15. The upper one is the newest. The lower right has the first iteration of an actual throttle (that I have). The lower left is, of course CL. The muffler is a bit heavy and I'm told some folks etched the insides with acid to make the walls thinner. I did not.
My MAX-II .15 has a baffle type throttle coupled with a rotating exhaust restrictor.
