I hope that people don't mind me adding this post but I have put together a little website.
I have been repairing all kinds of concertinas for a good few years now and I just wanted people to know that it's there and is an option for people.
I have a huge amount of people to thank for their support, knowledge and patience. (A lot of people read and contribute to this great site.)
I won't name people as I will probably leave someone out.
Thanks and best wishes to all,
Seán Ó Fearghail
