The TC-200, 201, 300, 301 do not work with pre-AI lenses at all, according to Nikon. A 50/2 H, unless it has been AI'd, is a pre-AI lens. The only Nikon teleconverter that will work with it unmodified is a TC-1. Some pre-AI lenses have a thin enough aperture ring that they will, surprisingly, work with AI bodies and teleconverters, etc, without damage. But, the 50/2 H is not one of them, at least the lenses with the scalloped aperture ring.
The one on the left is an unmodified H. The one on the right is a factory AI'd HC version. Click on the image to see it full-size. Note how the aperture ring on the HC has a ridge and that the ring doesn't have a "skirt" that extends down as far as the one on the H. The one on the left will only work with a TC-1. The one on the right will work on the TC-1, TC-200, TC-201, and the TC-14A. If your lens is like the one on the left and has the scalloped aperture ring, you can probably find an AI ring. It'll be hard to find, but they are out there. Lenses between serial number 742111 and 785010 that have the retaining ring between the aperture ring and the lens mount use the #3 ring. 785011 and higher use the #2 ring.
Hope this helps.
