Hi
The resistance felt at the clutch pedal is fairly small as the slack is taken up, and then suddenly becomes much greater as the levers move to disengage the clutch. About 80lb is needed on the pedal. Your diagnosis of a clutch stuck due to being left for years is probably correct.
Be aware that the clutch design is a bit back to front, and has a metal disc connected to the gearbox shaft. This is squeezed by one friction lining on the back of the flywheel and a second one the other side which is moved away by the release mechanism. The total leverage from your foot to the friction linings is about 8:1, i.e. a quarter inch of pedal movement will release the lining by 1/32nd inch which is enough to free it.
Although there are a variety of techniques to free off a stuck clutch, you might find it easier to remove the gearbox and dismantle the clutch mechanism to see what's going on.
