I bought this accordion from ebay for around 80euros. It came with a wooden case and it seemed in a very good shape.
Work done:
- Took tremble keys off and sand polished them.
- Sand polished the tramble grille
- Replaced bash side air cloth
- Added bellows snap buttons as the screws that it had did not keep bellows tight.
- Cleaned and replaced bellows sealing tape (6×3.00 mm black)
- Added new bellow pins (19×2.00mm)
- Replaced the tramble key rod (2.00 brass)
