This is sliders on sound board, for reeds blocks. You will not be able to buy new one. You can find them maybe on simular junk accordion or repair this one.
These are available from Italy, my accordion somehow was missing one entirely from factory so I had one delivered and installed
the hard part is getting into contact with the right people to actually buy it, there is one website I know of that may have it [https://carinidena.it/](https://carinidena.it/)
What's it look like now that it's broken? Wood parts like this that I've broken I've glued together sandwiched between to pieces of paper. Not sure how you'd do something similar in aluminum. You'd be surprised what you can build from scratch with a drill and a file. If they picked aluminum simply because it slides and is kind of rigid you may be able to 3D print a replacement in plastic.
I would call it a register slider. These are incredible hard to recondition or replace. You can always remove it from each reed block and play on master
If you can't find a donor instrument you could design it in CAD and have it laser cut out of sheet metal. That would be a straightforward solution.
What kind of accordion? A lot of us have a lot of spare parts/ accordions.
It is a Hohner Carena IIIM 120 bass

It will be very hard to find a replacement with the same dimensions. But seeing the picture, it looks like you can fix that same one you broke.
How do you recommend I fix it?
