Ironshod boots were in an equipment article in one of the original early Town Cryers. For a small sum of money you could add an extra attack to any model. I think it was deemed too powerful, and it was removed from the Town Cryer Annual and any online versions of the literature as far as I know. Not sure on the brass knuckles.
Personally, I think it's fine the boots were removed as they're unnecessary, but if your group wants to use them then why not?
