hello to you . I'm looking for an old accordion strap. Let me explain: when I started playing the accordion, I had straps with a back ring with 4 belts equipped with 4 metal hooks that allowed me to remove and hang my accordion without help. Here, I have a Roland accordion with comfortable straps still attached to the accordion, with an addition with clips to hold my straps together at the back. If you have this model, please let me know. Thank you in advance. Musically
