Help identifying demon carburetor please.

[DIGGMAN]

CAN I GET SOME HELP IDENTIFYING THIS DEMON CARBURETOR.

THERE ARE NO MODEL NUMBERS ON IT AND I WENT TO THE DEMON WEBSITE TO TRY AND IDENTIFY THE CARB WITH NO LUCK.

WAS HOPING SOMEONE ON HERE HAS SOME EXPERIENCE WITH DEMON CARBS.

HERE IS THE SITE.

http://www.demoncarbs.com/Tech/Identification.asp

ON THE BOTTOM OF CARB ARE TWO SETS OF NUMBERS 156 AND 169

ANY HELP WOULD BE APPRECIATED.
