This accordion is amazing. It has a switch to select EAD, GCF or BbEbAb keys. It has 23 helikon basses. The entire bank of 5 treble reedblocks shifts left/right to align the reedblock holes with the button pallets. 

For the restorer or adventuresome enthusiast I am willing to sell this “as is” for a much reduced cost versus restored and tuned.
