I have a ms111 coin mech that i have for uk coins. I uses 20p,50p and £1 coins.Luckily it was with the machine when i bought it but i got rid of all the wiring as the cab was knackered and rewired everything into an ipac with the bits i needed for the coin mech which was basically 12v+ 12v- and the common and normally open wires for the ipac.
I think pretty much any coin mech will fit.
