Hi. When I was very young I found an old dusty piano accordion in a library under a table. I was taking piano lessons at the time so I figured some things out and was able to play some popular tunes by ear on it. My father bought me an old 80 base piano accordion and I just played for fun. Later I stopped and continued studying the piano & violin for some years. I performed on the piano in my piano class recital and was a string player in a community orchestra. My fascination with the accordion was still there so I bought this accordion in 2002. I started trying to learn it for a few weeks. Then things happened in my life and this stayed in the case for 22 years. I just took it out of the case today to test it. Everything is in great shape-keys, bellows, etc. I’m lost though. Not sure what type of accordion this is. I tried looking it up on line but couldn’t find much. I don’t know much about accordion types so I’m not sure what I have. I read some things about c & b systems, converter and standard, etc. I would appreciate some help. Photos below. Thanks.
