it's a 9300-807 5-price die cast metal) model, #1 is called a CREM (Coin-Return-Electro-Magnet) it's used to reject coins if the machine (coinmech) is out of change (nickels), it's been disconected on yours, but it isn't required for home use, and it won't affect the functioning of the unit. 
#2 is the coin-counter relay coil, without it, the mechanical coin-counter won't advance (rotate) & the machine wouldn't know what the vending price is set at), as for a manual, you could contact COINCO & if they still have a file copy they could download for you, although it is obviously an obsolete coinmech. sometimes they do have a set of prints still floating around.
