As a Professional Musician of 20 years, I have noticed many Hohner Corona Models beautifully pictured and listed as original or traditional. However, while the Corona II model that is up for sell may actually be an original Hohner Accordion, it may not have the characteristics of the original, older Corona II models. The clear obvious is the back of the finger board. Newer models, unless specifically made from the Hohner custom shop, are cheaply designed and resemble the manufacturing quality with plastic finger boards, buttons and even moving parts. This is typical of the International model. Whenever someone is selling what they claim to be an original Hohner accordion, but they don't list with pictures of the buttons, finger board back or even the inside reed blocks, always ask for pictures and verification of wood-built before making a bid. There are also various accordion repair specialists scattered throughout the nation, so asking a seller to get a letter of verification from a repair shop is not out of the question. I have traveled extensively, so feel free to email me if you need the listing of a repair specialist near you or the seller.
