I don't have one of these to look at, but lenses are frequently held together with thin, threaded rings surrounding each element. Look at the front element, and see if the ring closest to the element has a couple of notches in it, 180 degrees apart. These rings are removed by unscrewing them with a spanner (generally a horizontal bar with two adjustable, vertical pieces whose ends fit into the notches). Unfortunately, however, getting to the internal elements frequently involves taking apart minor things like the focusing movement, removing the diaphragm, and other easily broken parts. Getting everything centered during reassembly is fairly critical, too, if you care about optical performance.
