I noticed he was wrong too, but I only considered it worth mentioning when you copied the mistake. Robot arms are not unheard of (-->wormtail aka. peter petigrew) but I doubt it. otherwise he wouldn't be called one arm.
Thanks for the input, Casey, I really appreciate it ^^ Oh well, I'm too lazy to fix the picture so let's just ignore the mistake and hope nobody will notice now that I've change the description from 'Bahry the one-arm auror' to 'Bahry the auror'
