I can't get a response from that guy... or anyone else for that matter. However, I have found two other prospects to purchase from.
These sound like better deals, and they have pic's of moving parts as you asked.

and they are cheaper!
I hope one of these is the one, I dont know how many cm the blue one is and the yellow one is 61c. I hope that wont be too big, I think 58c is what I should have. but maybe it wont be too big of a difference. Anyways what do you guyz think?
