What I need to know is if there's any information on Sirius Black's wand. I've tried the Lexicon but they have '?' under wand.

I'd like to know length, core and wood. If there's any canon evidence about this then great but if not how do I go about choising the wand for the wizard?

Any help appreciated.

My plan is that he'll get a duplicate wand after escaping from Azkaban.
