antique Arion accordian Germany Steel Brass Reeds Needs Repairs

Description

antique Arion accordian Germany mop keys.
There should be 5 of these mop keys on the bass side but one is missing
The keyboard side is 21 knobs of which 2 are missing
The bellows appears to be in quite good condition. There are a couple small holes in a couple of the end folds
It does play notes but not super well. Making music would require someone who knew what to do with it
No date that I can find
I assume there were 4 wood knobs on the top at one time. Now we have 2. Not sure what they are for
The closures to hold it shut no longer function
Repairs would be needed to make it play as it should
Very old and hard to find especially with the hood bellows
The frame seems in tact as well
This is a small accordian. About 14x14x8
