See below as an example http://www.sunnysteel.com/barred-tee.php#.VYxyFppwbbV The original ones were literally bars welled abroad the branch. Modern ones are much better and much more likely to still be there many years later. Remember - More details = better answers Also: If you get a response it's polite to respond to it.
