Delicia Arnaldo 23 piano accordion, 72 bass, three sets of reeds, seven couplers, two bass couplers. Made in the Czech Republic. This instrument was a factory return with bass button issues. I have repaired the bass machine and the instrument is now mint condition, fully functioning. This is the current Arnaldo 23 model on sale new for around £1400. It is a beautiful accordion in black, with hard case. Please see the demo video.
