Thoughts on seeing those pics - One doesn't normally separate the claw from the derailleur, especially with it still on the bike! One reason is that its mounting is integral to the spring tension of the upper pivot. Simplex used different threads from everyone else so theirs aren't swappable to a Suntour. However you can buy a claw from any co-op or LBS for just a few bucks.
Just curious (and perhaps you already said), what is broken on that Simplex?
