Unbranded red accordion.  SUPER finnicky.  I broke it down and replaced a majority of the leather valves.  Cleaned out the reeds with paper, replaced the hand straps on the outside and the mesh that covers the holes and made a new wooden button for the breather.  Still, it has some stuck notes when you really bear into it and the buttons like to push beyond the cover and into the body.  Tedious stuff.  Also, the straps that hold it shut are still missing; I couldn't find the right snaps to fix them.  It's missing one of the pins that holds one of the ends to the bellows, but that's just one of 12 so it doesn't affect it at all.
