Hello everyone from Spain, this is my first post and I write with the help of the telephone translator, so perhaps this or my future messages may include some formal errors, please forgive me if this happens. I am trying to gather information about my new Excelsior model 304 B accordion and I can't find much on the internet, so any information will be welcome, I am especially interested in the years of manufacture of this model, the construction quality, as well as the type of reeds that it has, I have opened it and I have seen that the reeds have the pyramid type rivet, I know that the hand or hand type reeds have that type of rivet but I wouldn't know how to differentiate one from the other. Also if anyone has any ideas on where to get the Excelsior letters that you see on the front, mine has a broken "E", I'll try to post a photo! Well that's all for today, thank you all for reading this message. Greetings.
