Vintage HOHNER?? Accordion TANGO 11 II B For Sale

I dont recognize the markings on this so maybe its a rare model? Irt looks very similar to a Hohner. Not an expert on these but I have played a little bit. My grandfather used to play when I was a kid. I dont see any major damage except some normal useage wear. All the keys appear fine and work. Nice hard case included. There are NO returns on this its a large heavy item and shipping is too much so its sold as is. Pictures are part of the description. Please ask any questions Before purchasing. I charge actual shipping. You can choose USPS UPS or Fedex at checkout to get the best rates. Thank you for looking at my listing.
