Originally the parts you list were chromium plated. If it is re-done properly with appropriate underplating, and kept clean the replacement plating should last very many years. The problem with chromium is that it is porous, so if you don't spend money on having it done properly with suitable plating under the chrome corrosion will set in. This is more of a problem on the steel parts than the brass ones.
