The only thing I noticed different with the model 21 images is this one doesn’t have a hollow cut out above where the serial number plate would be.

Thank you. I’m planning on selling it. It’s good to know it’s in great condition for being so old! The serial number has fallen off somehow on both sides. Seems blank on that oval part. So it’s valuable?

I have had this concertina I found for over ten years. I’m wondering if anyone can tell me ANY info about it based on looks. I really appreciate it. I can tell it’s old and would love some experienced enthusiasts to help
