Have no clue...as I only basing the guess on his casting of the valve body cause it looks like the one i bought back in 93....but the solenoid is mounted differently.....he makes what is called a Bracket Brake...which this might be....his Pro Brake is the one we use...and as said the solenoid is mounted differently
Still have no clue who make's this , wow this is a hard one , the guy I got it from sez it's a TA cheetah and he either got it from jegs or mancini's but can't remember for sure.
