Note of caution: This is not a modification you should try unless you have good experience working with accordions and making parts from scrap. The materials I use for making the oversize valves (German "Klapper") are available from the local Hobby store. These include spruce plywood, soft leather, thin foam rubber sheets, and assorted glues. Remember, any hole you make that connects the inner air chamber with the outside world must be sealed for the instrument to have proper compression.
Decorations: The "jeweling" on the exterior of this box was done by me. It does nothing to improve the sound or playability, but it definitely makes the instrument look special and pretty. Good looks never hurt any accordion.
These Morelli accordions have been advertised and sold on Ebay as "hard
to find", "rare", and "by Italian Engineering". After over a year
of selling these instruments on the web, those Ebay auctioneers continue
to claim that they were able to obtain "just a very few" of them.
My point? Be careful when dealing with anyone who takes such liberties
with the truth. To be sure, they are inexpensive (as accordions go),
but by my experience with them, there is little quality control on the
boxes, and they are only suitable as toys unless you are able to have a
good tuner-techinician go over them. I enjoy playing this particular
Morelli, but I sent it to a very capable and skilled accordion craftsman
who completely re-tuned the instrument and also re-aligned many components
such as reeds and linkages. My thanks and appreciation to Michael
