And there is a easy, tell-tale way of distinguishing Halo A from Halo B. First of all, how old is the hopper? If it is older it could be either(most likely A) and if it is new then it is the B. Next, look inside what color is the paddle cone? Black... then it's A, but if it is clear then it's B. And ultimately, how many paddles does it have, B has 6 and the A usually will have only 2. Hope this helped you out bit...
