Ah! I have a Rowsell built China Doll ( N2632 Dinsdale) in a similar state..........................................
 
On the Doll the plate  box was glued to the mouldings on either side of the ply case box and this was in turn glued and screwed to the hog. The screws had been capped off so were a bit of a sod to get out but once done the plate case came out relatively easily with the careful use of a very sharp chisel, being careful not to damage the hog in the process. I have kept the remains of the old box to use as a template for the new one.
 
In my 'case' (pardon the pun) the glue was on the verge of failing and in reality the very corroded brass screws and thwart were all that was actually holding the assembly in the boat.

thanks a million for the advice
i am going to have a crack at that in the morning
cant wait...
What was the condition of your bottom planks when the case came out?
just so that I have an idea what to expect...

thanks again sir
