(I DON'T KNOW MUCH ABOUT TRI-PODS AND COULD NOT FIND A MODEL NUMBER ON THIS ITEM.  AFTER I TOOK PICS I DISCOVERED THE LEGS UNSCREW AND ADJUST TO HIGHER HEIGHT.  MEASURING FROM TIPS TO TOP WITH LEGS EXTENDED IT IS ABOUT 56") THIS WAS MY FATHER-IN-LAW'S TRIPOD AND DOES HAVE SOME USE MARKS.  APPEARS TO BE IN VERY GOOD CONDITION.  ANY QUESTIONS, LET ME KNOW AND I'LL SEE IF I CAN FIGURE IT OUT.
