What are you trying to do, build a complete set with of the system with the original box and manuals that it came with?
I think you've got a lot of variables involved, for example C= sold many different packages of A500's, all of which I would assume came with different manuals based on the included software, what ROM version it has, etc. At best all anybody would be able to give you is an educated guess, but assuming your system has one 1.3 ROM's that photo you posted looks good to me!
