Hopefully, the pianist will not interpret Ped. al fine to mean Ped. sempre.
But I do understand that Hector Pascal means "depress the sustain pedal and keep it down until the end of the movement."
Ped. sempre placed at the beginning of a piece would mean to me that the sustaining pedal is to be
used throughout the piece in the standard way, not that it should be held down without ever lifting it throughout the piece. I am was concerned that Ped. al fine might be interpreted in the same way as Ped. sempre and thus a more elaborate Italian direction might be appropriate in this case.
Holding the pedal down throughout a piece is not a common effect. The debate about Moonlight Sonata hinges on the theory that Beethoven's piano had less resonance, so holding it down throughout all the changes of harmony might have been acceptable musically to create an eerie effect somewhat like holding down the pedal on a modern piano only enough to catch a little of the resonance (1/8 pedal). However the usual interpretation is that the pedal be used in the standard way, constantly depressing and lifting it to clear the melody and harmony.
Yes, senza sordino means depress the pedal so the dampers are off the strings. It is canceled by con sordino, let the dampers down so they stop the strings from vibrating. Here is an example from the third movement of the Moonlight Sonata:

This was a totally counter-intuitive and cumbersome way to show pedaling, and Beethoven changed to a Ped. 0 system soon after the Moonlight Sonata. As David Ward mentioned, Beethoven's piano had a muting device much like the current soft pedal, that shifted the keyboard so that only two or one of the three strings was struck by the hammers: due corda, una corda, and tre corda, which meant normal position with all three strings struck.
It is not generally known that the muting effect of the soft pedal is not only the striking of the two strings instead of three, but also the effect of the hammers hitting the strings in between the grooves that are formed in the felt by constant hitting of the three strings per note. This means that the soft pedal can actually produce more than one muted sound by various degrees of depression. This is an underutilized effect and one unknown to many players.
