But for the word "English" I would suspect these as being Hupfeld
Clavitist rolls, similar to Animatic, but in their 20,000 series.
These were "themed" rolls of pop music with coupler instructions
bringing in glockenspiels, castanets, drums and the like.  The Musical
Museum at Brentford has a Clavitist "Jazz Orchestra" using these rolls,
but its music is distinctly of the Original Dixieland Jazz Band era,
or even just Tin Pan Alley ragtime with a (somewhat arbitrary) rhythm
section added.

If the music is definitely identifiable with the large British output
on "Themodist" (never "Themodist-Metrostyle", by the way) and Universal
"Full Scale Accentuated" rolls of swinging 1920s dance music often
originally mastered for Mel-O-Dee in the States, then Phil has a real
rarity -- some specials made up for the British fairground/cafe market
by, presumably, Bluthner & Co., Hupfeld's agent in London, or even
Universal Music Co., the Aeolian subsidiary roll maker at Hayes.

If nothing else, the spool ends will betray which: wooden, or black
composition (old 78 rpm records melted down) ?

I think the Clavitist used the Triphonola (reproducing) tracker bar
for the extra ports, but these can't possibly be Triphonola rolls.
Why not ? At no time did Triphonola ever issue rolls of any description
which _swung_! (Perhaps that's why it failed ?)

Are there no labels or other clues at all ? Little rubber stamps ?
Dates ?
