If the bases are as old as your boat and are chrome on bronze they are most likely Lee's or Perko. If they are Lee's they will have their logo/name on them. Lee's no longer makes the bases or holders in the 1 1/8" size but still makes the poles. There are several other brands of elbows and poles available. Some will fit Lee's bases, some won't. If you can find the elbows on ebay or craigs you would be set. The elbows would be the key. Dave
