Accordion opinion

That is one very high styled accordion. I love it!

The styling mimics the front of a 1958 Cadillac.

The most likely answer to the problem after this discovery is that a the (leather or plastic) valve on the outside of the reed block has fallen off or is stuck open. (Fallen off is most likely.) You have to open up the accordion and look. Pull the bellow pins on the treble side and lay them aside in the right order. Lift the treble case and turn it over. It should be easy to spot the position where a valve has fallen off, and as the accordion is normally a closed box you should also find the valve inside somewhere... Take out the reed block, glue the valve back on, put everything back together.

I concur with Mr. DeBra that a deformed, stuck, or detached reed skin is the most likely cause of the problem. That would be easy for you to find visually (since the problem occurs when you compress the bellows) and fix yourself in the manner he describes. The traditional adhesive is thickened shellac. However, any other adhesive that holds well for attaching leather or plastic to metal will work. You just don't want to use something like super glue that can't be later removed.
