ok then lets think this through once and for all
your concern: "Now, for me, the biggest dilemma"
and i need to see (a photo of) the shifts
the 9xx series was entirely built from scratch in the CEMEX factory
from raw materials by the Excelsior workforce
lower export series designed for the American market, for example,
were not part of the 9xx line, and were clearly indicated as separate models
with (usually) model numbers like 1480 and such, and they were never
suggested as being sister models, but were a level above the Accordiana
or Excelciola lines
the specialty lines like the AC and Symphony were equal to the
9xx line for build level while having their own special or unique
features/engineering/gold plating etc.
while they shared much, the biggest difference was common
shifts, keytops, buttons, and other mundane hardware that
could be purchased in bulk from the third party suppliers at that time,
and the reed-quality of a standard 14xx model, which typically
the reeds were referred to as "export" quality which meant generic,
unmarked, machine made (but obviously pretty damn good) reeds
these lines all sported teardrop shifts, as a dead giveaway,
and obviously need more "squeezing" than the pro models
however
special order pre-paid units could be had with any level of
reeds and tuning CEMEX had available, and so occasionally
you find a teardrop model with equivalent playability in
touch and tone that was ordered and imported through
ALAS or Castiglione
as far as if they officially said this was a sister model, then the
obvious/only difference to me would have been they specially treated the
wood and felts and leathers to resist the termites and other bugs
which were an intense problem for any product of this type
intended for the South American tropical marketplace, but would have
been a waste of money for other markets
I'll try to organize this message in a way that's makes it easier to read and reply to. Hopefully I'll succeed
Some additional information regarding this specific accordion:
- After inspection, I can confirm that it has a mano reads with "Cagnoni" marked in them;
- I can also confirm with 100% certainty that this specific accordion has the extended low bass from E feature, which can only be added if requested by the client;
- The name of this accordion's line is "Mod. 2000". However, this specific accordion is marked as a "Mod. 2000E R".
The most relevant info Excelsior was able to share with me regarding the "2000" line and this specific accordion:
- "the “2000” product line consisted of accordions specially produced for the Brazilian Market until about the end of 1990’s";
- "Based on the photos you sent us, we can tell you that this model should be a professional model with Cassotto and equipped with A MANO reeds";
- "We can just add that this model 2000E R was similar to model 940. Unfortunately we do not have any other information about it, nor brochures";
- "Regarding the extended low bass from E, we have no way to tell you if this accordion was equipped with it or not. Data sheet of the “2000” product line is no longer available. Generally speaking, we can tell you that sometimes it happens that customers require this special feature."
Now, the final questions (hopefully):
1) I'm unfamiliar with the term "shifts". What are they?
2) So, in short: the export lines of professional accordions had the overall quality of the 9xx line but, in order to cut costs, Excelsior used commonly found third-party hardware like buttons, keys, etc. and unmarked machine made reeds?
3) Is it safe to assume that, since this specific accordion has "E R" added to its name, the extended low bass from E feature and Cagnoni a mano reeds, it may fall in the "special order pre-paid units could be had with any level of reeds and tuning CEMEX had available" category?
4) Is it possible that this wood treatment for the South America region is why it's so hard to identify the specific wood used for this accordion?
I hope that these questions cover all the final points. I'll send the photo of the shifts as soon as I know what they're exactly o7
