49T and 52T chain rings Dura Ace 10 mm pitch

Due to my own dumbness and some bad luck, I lost my 10 mm pitch chain ring.
But thanks to the great support of Neil, my British friend in Tokyo, I got this 49T replacement. For a very attractive price, like new and with a bunch of lovely stamps.
Now, the group set is complete again.

EDIT (2013/Sept/04): Lucky me! The postman brought back the missing 52 teeth chain ring, so now I have two, one with 49 and one with 52 teeth.
