Hi everyone,   I just bought a really tiny anglo concertina (on the right of my Hohner on the picture) and I have few questions for you.   Firstly, I have no idea of the quality, brand, year, so any identification could help me. (Edit: the reeds plates and wooden levers seems common in German-made anglos, so it's probably one)   My main problem is to fix the springs. I already replaced a spring on my Hohner, so I have the right equipment to create new ones
