re: "the clutch plate would have to be stuck [to the] transmission shaft"
The most plausible explanation yet. Sitting for years, esp. in a damp
climate, the splines could very well 'rust-weld' together given their
small clearance. I don't know if it's common practice, but I always put
some tenacious grease, usually wheel bearing grease, on those splines
(thin coat only).

<br>
I think if it was just the clutch disk stuck to flywheel
you'd still get at least some movement of the pedal. Early
cars used coil springs in the cover plate to hold the disk
firm to the flywheel, and later cars used diaphragm
'springs.' I think with either you'd at least be able to
move the pedal until the springs reached their limit of
travel (or you left leg reached its limit of strength). <br>
<br>
It's a long shot SWAG, but since the car has sat for a long
time it's conceivable the fluid in the line has gelled
and/or crystallized to the point it prevents flow to the
slave cylinder (I have had BF gell up). I'm not sure you can
move the release bearing fork much by hand, though I haven't
tried; those are some strong springs in the cover plate.<br>

Maybe the slave cylinder is locked up. Pull the
