I have a nice boxed Gremlin Tenor Treble (Tenor C to C) English Concertina that is not used now that I have my Lachenal New Model Tenor.
It plays surprisingly well for a modern budget box and it has a nice tone. It has a few minor knocks, but nothing of any significance.
I am looking for around £200 plus postage.
I live near Glasgow, and potential buyers are welcome to come and try before purchase.
