I don't play any musical instruments and have a Scholer Concertina with 10 buttons on one end and 10 buttons on the other end with a button that releases the air in the bellows. Know it is a Scholer as it has a gold metal piece with two birds on a globe. Got it from my father-in-law when he passed away. Never knew him to play it and do not know where or when he got it. It is in a 6 sided green box and look like it was never really used. The only identifying marks on the concertina are a sticker that says double organ and plate that says made in Germany East. The ends are capped in metal and have metal corner plates. It has 4 sets of bellows with three plates between each end. The outer bellows consist of 3 sections each and the two inter bellow sections have 2 bellows each. The plates and end pieces all have metal corner plates that are nailed in.
I have searched around on the internet and can't find any thing that can help me on the Scholer Co. Or any pictures of any concertina that looks anything like this one. Do not know if it is a junk one or a decent concertina. Any help of any kind would be appreciated.
