Jorge, that is terrible I don't know how they could loose something that big. If you have one of each part you may have to have them cast out of bronze. Then you would need to metal finish for ft and then chrome them. I don't know where you would find them, you can try Dave Babcock first. Good Luck and best wishes, Tim.
PS. Jorge I went to the International wet in Mansfield Ohio just three eels ago and talked to several vendors, no one had any Rockne parts. Did you ever here anything from the fellow that knew someone who had Rockne parts for sale. I haven't seen anything more about them on the forum.
