Malcolm, according to page 60 of your copy of my book (I am still grateful for the money, thank you) the bar is of silver steel. If you have not done so already may I recommend hanging the cables up somewhere convenient and applying (SAFE!) heat to persuade years of solidified grease to depart. I tend to replace with a lightish oil eg one's modern car's engine oil but often that is hardly necessary.
