Ah, so its the base plate coming away, a common problem on Hohner reedblocks.

How you fix it depends on how important the box is to you and how permanent a repair you want. 

If you want a quick fix an aren't too concerned about how long it lasts then superglue will capillary its way all through the crack.  Clamp it firmly while the glue sets.

To do a more thorough job you have to remove the reeds above the crack, enough to trace how far the crack extends.  Clean off all the wax and then try and work out what type of glue was used originally.  If it is an old instrument it is likely to be hide glue, a more modern one will have a synthetic glue such as pva.  Use the same type to do the repair.  You may also be able to put a slim woodscrew up from the base of the reedblock to strengthen the joint but position it carefully so it has something to go into.

You may also need to replace the gasket if it gets contaminated with glue.

thanks theo

im not sure of its age, but the glue that has been used looks brownish in colour..  this would be hide glue would it ??

what are you calling 'the gasket' .. is that the material the base plate sits on ?

Seems likely.  If it is it will soften with water, slowly with cold, faster with warm.

Yes, probably soft leather, I have some modern synthetic replacement if needed
