stick identification

hey i came up on a x arcade controller which appears to have been completely gutted and filled with new sticks and buttons. i dont know anything about the various brands of sticks and these are the best pictures i can get. the sticks are blue and yellow bat tops. the buttons inside say suzo happ but i couldnt find anything written on the sticks. ill try to get better pictures if this isnt enough
