There has been some modications to this one. The support brace to hold the boom up has a brace from the yoke where the boom swivels this has a brace going to the brace in front that runs across the body. This is so the top can be removed and the rigging stays the same. Then at the base of the boom I had to raise it to clear the ring that rotates the boom rotation so it will lay straight down to be supported by a flat car when transporting. this one also uses the MTL couplers.
