let me call your attention to the Keyboards in the Vid's that
Dingo posted near the beginning of this thread
the first one should be pretty obvious to everyone... that is
not a Zero-Sette build...
(look at the offset edge on the low F treble key)
actually many of you SHOULD be able to guess the factory
of origin based on that offset, which was set in stone
in New York before shifting to Italy (and the grille and shifts)
you can also determine the periods that had different
suppliers by the voluptuous sculpting of the treble
keyboard edge, vs the period using a more flatted line
dead giveaway to different factories
in the 50's and early 60's Giulietti did not source from Zero,
then they made a deal that included (very limited) European
distribution rights, and from that point both Guilietti and Petosa
sourced their accordions from Zero through the 80's... Zero
continued the styling from the other factory for Julio
(note the sculpted space fillers around the 120 Bass buttons)
Zero had a large and very complete factory during this period
including Actions, Bellows, Keys, and an Acetone room -
and of course made their Bodies in house... Physical carachteristics
of Zero bodywork and dimension is noticeably different from Bugari,
as you can see from the 4th Video which is clearly a modern Bugari body
the 3rd Video IS a Petosa from the Zero factory... i played it
during a visit to Seattle and know the model... yes the Bass
is bad-ass and it is a heavy beast but strollable if you take your time
(which i did playing the stately AMBOSS Polka)
the second vid with the reverse color keyboard has that very flat planed
treble edge
the original Zero factory outlived the Gulietti company, and
after G was closed in the USA, Zero still retained the right to
build and sell them in Europe, and so for several years longer
that Giulietti existed, new models WERE available (then glommed
onto eBay, then the Heirs in America got angry, then...
about this time Zero did go out of business, and closed their factory.
Legally when they dissolved they lost the right to the Euro Giulietti
though there are a few post-zero Bootlegs that continued to
pop up in Europe (but are obviously not Zero's OR Bugari's... look closely)
during this period Petosa had to find a new supplier of bodies, and
so their original and famous looking models with the nicely curved
and sculpted lines ENDED with the bodys they had IN STOCK at the
time of Zero's demise... things are vague from this period but the IMF
factory that got set up during this period may have had an assist
from Seattle interests as well as the Gabbanelli and Piermaria families...
about this time Bugari stepped in and made a deal to help Zero
re-emerge as an entity, which was rather nice of them... BUT it
should be obvious to you all from examination that Zero was not
able to save their tooling or body forms, and now builds all of
their models based upon Bugari bodies (and presumably actions)
so while there are obviously nice and well crafted accordions
coming out of there today, they are DIFFERENT than "of old"
and they do, again, supply most of Petosa's line...
to my ear, Bugari has always had a certain sound, and they
have always been damn proud of it and their reed-work...
i think it has always set them apart from the other builders...
todays Petosa models are going to be re-fined in Seattle as they
have always been, and will show and play like Petosa's, but they
will not sound or feel the same as the models that made them famous
and as such should be evaluated not on reputation or historical legend
alone, but upon YOU playing the accordion you are considering buying
and evaluating it with your own ears.
finally, Petosa had obviously made a limited rights deal with the heirs of Guilietti
and offer several models, but it is not clear from where they were sourced
or if this is a continuing objective or was a one time arrangement they
will eventually sell through and out... current Bugari bodies do not appear to
have that telltale offset except on extended keyboard models
examine closely is my advise
