yes the Roselli is early 50's and is simply too old to still be in
excellent condition. It has waterfall keys which i advise people to avoid
like the plague
it's value is totally dependent upon an internal inspection to find the
reed configuration, and condition of the reeds and valves
however
the cream and blue aluminum model is one of the nice, lightweight and
bold sounding Scandalli's from the 1960's. This one is in LMM reed configuration,
and on these, typically means a sweet sounding Meusette tuning as
well as a strong Deep voice and full sounding master registration.
the condition of these is often dependent on how the rubbers aged..
if they have dried and cracked off (in the Bass section most evident)
if you turn one of these upside down so the buttons point down and
give a gentle shake, if a few become "distended" then some of the
rubbers are gone. tedious to fix, but not difficult to do
sometimes the bellows catch (in the back, you twist it to free or lock)
gets bent out of shape, and the gasket can leak there more easily than
the rest of the bellows edges
these models are a delight to own and play, with nice sound that carries
well and easy key-action and a palm master switch on most of them.
They came in 2 sizes, so measure the width of the piano keyboard
edge to edge and report that on your sale advertisement. The 3/4 size
model is ideal for outdoor strolling, Nursing home gigs, busking..
experienced Accordionists likely know this model has the Scandalli
individual pivot Treble and full drop-out Bass innovations of the time,
which makes them easy to work on and repair. in addition, the Treble
keypads introduced a self-leveling component to accordion-building,
so this nice looking box offered several technological breakthroughs.
many of these were made, they offered a lot of accordion for a bett
price at the time, but now would mostly be useful as the handy accordion
you grab and go with for everything you do NOT want to take your
big, heavy Professional accordion out for
