A French colleague successfully tried a compilation of the rolls
which were available for the aforementioned instrument which was
launched in 1931 by Rene Seybold situated at Strasbourg, France.

As I found out, up to now there were only a few accordion players
who signed for the most of the rolls for that instrument, as are:

Hermann Schittenhelm (b. 10. September 1893 in Boll, [Oberndorf
am Neckar]; d. 20. February 1979)
( https://de.wikipedia.org/wiki/Hermann_Schittenhelm )

Albert Carrara (1903-1968), a well-known "Musette" interpreter at
the time.

There were also a huge number of rolls produced and recorded by
Seybold himself with kind of a pseudonym, as was R. A. Dlobie (if
you read the name backwards it was "eibold").

But there are other interpreters I couldn't find anything about:

Ferro Carranza
Wolferstetter
Piétro Léonardi
Fred Nicolai
H. Bastien, which could possibly be another pseudonym of Rene Seybold
himself? This name was used on early rolls and never used after rolls
which were signed for by R. A. Dlobie.

Is there anybody out there in the world of mechanical music and with
knowledge of the accordion-scene of the time who can help to identify
those interpreters who must have been well-known players of the
accordion in the nineteen-twenties and 'thirties?

I would appreciate any hints on the accordionists listed above.
