This is gorgeous! 
A primitive handmade trunk, not too big, with blacksmith made hinges and handles. 
It’s very old, possibly mid 1800s. 
It has been wallpapered at a later date with this delicate floral wallpaper, which has gradually worn off in places. 
You can see the difference at the back to the front in the colour, so the box must’ve been against the wall.
