For me this one remembers the pealing of bells
That's exactly my reaction too. Rather nice.
I have seen in Russia people play bells as if they were a "keyboard" (for lack of a better word) A number of them are hung up in the same manner as tubular bells are, cords are attached to each of the hammers and joined together in a knot. The performer then holds the chords by the knot and, by moving the knot from right to left and at the same time twisting it, plays a melody.
Interesting. From your description this appears to resemble a primitive form of carillion, which really does have a keyboard. Except that the "keys" are more robust than those of an organ or piano and are more like large levers sticking out of a huge panel. They require more force, and travel through a larger distance, than the keys of a piano or organ, and are therefore not really playable with your fingers, you use your fists instead.
Since the score is "secret" I can't comment on any misreadings, but the piece doesn't sound as though it conceals any rhythmic pitfalls. (No. 2 looks worth trying!).
A small technical point not related to playing: You seen to have developed a system whereby you enter the composer's name once and it magically appears in three places at once, namely the MP3 file name, and the composer and title ID3 tags. On this occasion you've mis-spelled the composer's name (by transposing the 'l' and 'g') which has therefore affected all three places.
