I cant help with the actual issue but I can answer the other question. The only way to get the missing accessories for cheap is to buy the KO version of MP 36. Its the same it would cost if another 3p company released just that extra stuff I guess.

And you asked me questions about the coin. I dont ever deal with canadian companies for MPs, so I dont know if they send coins or not for particular releases. All I konw is that any coin you find on e-bay is the real thing since there are no coin KOs.
Hope that helps.
