international business machine

Hello~

Could anyone tell me which of the following is/are grammatically correct?
And the reason why the others are wrong?
Please also tell me which one sound better in English.

1. "international financial machine"
2. "international financing machine"
3. "international finance machine"

Some of my friends tell me that only the 1st one is right, but the long form of IBM is "international business machine", does this mean that the 3rd one is also right?

Please help.

I think the third could be used. It's hard to sound which sounds the best without having an idea what the machine actually does, though the first sounds the most likely candidate. I doubt that the second would work.
