Help with vendo v156-276,

I just got this machine and would like to know everything, HELP PLEASE

Since this post I cleaned the coin mech. and it takes money and I reset the coinn amount to a quarter and it works. Will put cans in it to see if they drop. Says Desired bottle location nothing about cans. Probably early to mid 70s model. Any Ideas? But i need a bottle opener because the one is missing. Does anyone have an original or what would work? Can get specs on screw location. Thanks in advance, Mike from Walla Walla
