Hi.
There's also a grey arm with a hook hand. Don't know where it came from but I used it for a wounded ACW Rebel once.
I took a minute last night to decapitate a couple of pirates to see how a hook-hand peg-leg pirate would look. This is the result:

Btw, I know the story of this poor pirate. His leg was ripped off by a cannonball, then he lost his right hand to a hungry barracuda. When, he had his leg and hand "refitted", his eyelid tickled a bit, so he scratched....with his hook!

Cheers.
Arnaud
