My 1983 Trek 700 has Superbe derailleurs, cranks and brakes.
The levers are model LD-2000 and came with white rubber covers over the ends. The rubber covers were deteriorated so I took them off. These look a lot like the original Cyclone levers.
Here's a link to the 1984 Suntour catalog showing the LD-3200 levers pictured in the OP's first message.
