Hi paper strip musical box friends,  concerning the MMDigest
postings of Roger Gonnissen 12.01.25.01, Nancy Fratti 12.01.26.03
and Gérard Dabonot 12.01.26.04, there is an effective British trader
who sells new 30-note paper strip musical boxes like the one Roger
Gonnissen described as his own:

  N J Dean & Co, Exquisite Musical Boxes and Gifts,
  Goodfield House, 192 Bath Road, Keynsham,
  Bristol, BS 31 1TF, England
  http://www.njdean.co.uk/ 

At N J Dean's web site exactly this semi-chromatic paper strip
manivelle is offered for self-punchers.  The very special musical
scale of its 30 notes is: C, D, -, -, G, A, B, C1, D1, E1 full
chromatic to C3, D3, E3.

At this web site (follow -> Teanola Street Organs ->Musical Movements)
there is a short description of the music box in words and in photos:

However, the hint-sketch for joining strip sections in order to achieve
longer tunes is none too feasible:

Instead of that I prefer the better matching system of a Leporello-fold
and rectangular joining cut lines at the alternating ( front / rear)
Scotch tape hinge-joints.

N J Dean's price for this semi-chromatic 30-note movement is
astonishing low (ca. 40 GBP, i.e., ca. 60 euros; plus shipping costs)
and includes paper punch tool and instructions, 1 blank strip and
1 pre-punched tune strip.  Additional blank strips are available, each
is 1 GBP.

However, the music of the single pre-punched strip ("Happy Birthday"
as a simple audio sample) is wholly unsuitable to demonstrate the
particular musical potential of this semi-chromatic instrument.  In
order to exploit that it will be necessary to create an likewise
particular repertoire of well arranged tunes either by professionals
(and then selling for an adequate price) or by engaged hobby musicians
that do not shrink from beginner's frustrations but are willing to
learning by doing stepwise.

So far I know, this 30-note movement is up to now not common at the
corresponding German market -- perhaps in UK?  If you are able to come
to terms with its particular scale it might be a very inexpensive
alternative to the 33-note movement, with its nearby full chromatic
scale (C, D and then continuous chromatically up to A2), however too,
with its inexplicable high price: ca. 400 euro at the European market.

Newcomers at the music box product market will solely then establish
themselves at the market if from the beginning there is a sufficient
broad basic repertoire of fine and professional arranged tunes that
show the possibilities of making good music for and with this instrument
as an encouragement to punchers to become creative themselves as well.
Missing of convincing examples (or only "Happy Birthday" again and
again!)  will lead none encouraging and none commercial success to, too.
The selling will be limited to fortuity-buyers who don't know what to
do with it or to only rare enthusiasts who are able to discern the
possibilities of such a little machine for musical use creatively.

This prevails as well for introducing the chromatic 33-note Sankyo
manivelle at the American and European market two years ago!

The cat bites her tail:

Only few or none convincing music samples
-> only low or none interest in buying such a (cheap or expensive)
manivelle
-> low or none economical interest to commission attractive musical
arrangements
-> low or none interest in buying such a musical machine
-> and so on...

Look at the market for the similarly cheap and more widespread
offered 20-note diatonic Sankyo manivelle and its respective sets of
pre-punched music strips offered by many traders all over the world
(non-commercial free distribution music strips also by singular
enthusiasts like me).  This manivelle surely will continue existing
over the next 30 years and more and will not disappear again like the
former 30-note Sankyo in the early 1990s after a short ca. 3-years
life.

Confident regards,
