type of one piece key formed of and entirely in plastic,
with a rounded or sloped nose - as opposed to the typical
key made of wood, with a flat plastic, ivory, celluloid, cellulose
or (nowadays, typically) Lexan keytop accompanied by a small,
separate piece to cover the wood tip "nose area"
not wanting to muddy up the Ranco thread, but for
future readers maybe i should post my reasons
for reluctance towards the waterfall keys
and it's great when someone DOES find one still
with some life left in 'em, of course, but
generally speaking:
Plastic absolutely has a finite lifespan
Plastic is inherently brittle
that lifespan is considerably shortened if
subject to high, extended temperatures
(like a hot attic)
or extended exposure to Sunlight
or exposure to air rich in volatiles
or exposure (during cleaning) to reactive chemicals
early plastic technology was not advanced enough to
formulate protection against UV light (it was ages
before they even realized the vulnerability)
nor did manufacturing generally even understand
that plastics of the time were not 100% stable
and could become reactive under various conditions
(actually, some OEM's still don't seem to understand that)
this results in the obvious - that a Waterfall key if
broken will require you to MANUFACTURE a replacement
somehow (because you will simply never find an
exact spare unless you find an EXACT accordion
match same year same assembly line to butcher for parts)
so esthetics aside, it is advisable to those of you
who want an old accordion to fix up for fun and laughs
to, as a general rule, avoid bidding on ebay treasures with
waterfall keys... resist...
and if you DO succumb to that unusual accordion,
hopefully you find one like Jack did that is cool
enough to be worth fixing up a bit...
in other words, the plastic keys are an achillies heel...
no matter how much you fix up the rest of the accordion
once the keys go south on you, that's the end of it.
