My father in law purchased a melodeon (Organetto?) from a yard sale for my son for christmas. It is not an instrument that anyone in my family has ever played. I looked it up by model number and could find very little about it online. I found several articles where people were selling it, but I am not interested in selling it, or price. More I would like to know how to learn more about it. How old it is, who made it and the story behind this beautiful instrument. On the playing side, it says D dur on the side which I know to be a D Major scale in germany where it was made, however when played it doesnt seem to follow the scale the way I would expect. This could just be me being unfamiliar with the instrument, but is it possable for the melodeon to be out of tune and if so how would one go about fixing the issue so my son and perhaps myself can learn to play it properly?
I should add just in case you can not read it in the image the instrument says Pat. Holders Milano Organetto D.R.G.M. 362041 and the metal badges say Milano Organetto Made in Germany Which tells me although manufactured there it was not meant to be sold there because Germany is not called that to those who live there.
