Hello all! I'm very new to this, I just got a used concertina and am having a blast with it. However I've noticed a sizable hole where the bellows meets the wood. It leaks a fair amount of air when I extend the bellows to a certain draw and has made some songs more difficult to manage. It's an old instrument so there are a few other little holes, but as far as I can tell this is the only one that poses a real problem. I attached a picture so people can have a better idea of what I'm working with. Is there some kind of patch or glue I could use to minimize the air escaping? the location of the hole makes me think some kind of patch is possible. Thanks for your help!
