Vintage armonica " Cav. M. Dallape Figlio Stradella Italia." The letters and drawings are made of mother-of-pearl. Working, play 90%, i tested. All keys, buttons, arms, reeds is s okay,see in photo, of course need adjustament. Below need repairs, see in photo. Needs care small repairs. I wiped the dust but I didn't want to wipe my arms, I was afraid of making a mistake. This is a very rare accordeon, I think since 1924, writes inside. With a few small repairs you can have a wonderful accordeom. The sound is very strong. I wrote that it doesn't work, but as I wrote above, accordeon works 90%.
