Who played the two 'Iron Lady' executioners?

Does anybody know who played the roles of the two shirtless, hunky guys in tights who placed Lord Clancharlie inside the "Iron Lady" torture/death device at the beginning of the film? I looked through the full list of credits and there are quite a few male actors listed as uncredited, but no one is listed as playing an executioner. I guess it's possible that they may have just been extras who weren't even listed as uncredited actors, or they may have been part of the film crew.

If anyone could shed some light on this, I'd appreciate it.
