A 203 is a chain driven t acse and you can usually hear the chain it when ytou more the yolks. The 205 is gear driven and SHORTER. It aslo uses two round rods as the shifting mechanism, connected to a singled plate. The shifter itself mounts on a large stud on the 205, where the 203 has a flat arm. I don't think I am describing this well, and will try to attach a picture of my NP-205 for you.
