I think more of the counterweight has been put on the inside of the machine, to increase visibility to the rear. Ask the dealer if you can get a orange cast iron weight mounted to the back of the V519. It can really increase lift capacity.
EU version TL26.60 is the same as V519. Another model is the identical TL30.60, but with 900 pounds extra lift capacity, which comes from that extra cast iron weight (as shown on image) and possibly some internal weights. I think you should be able to get the cast iron weight on your V519 aswell.
