Secret hiding place

Had a text from J today while at work. She was home with the painter and they were looking at where the shutters will be fitted and notices some hinges. After ripping away the current shutter cover they found a small hidden box. Nothing in side but nice to see. Just need to get it patched up so we can keep it. Might even get a safe fitted instead. Finished early as got a cold starting hope it won’t come to much
