Gorgeous antique wooden portable stationery box. 

There is a lock mechanism but I don’t have a key to fit it. Unsure of the wood - possibly mahogany - a rich reddish brown and straight grain.
The exterior design is quite modernist. Clean simple lines with no fuss! The interior is a bit different! Lined with green felt with lots of fuss! The inside of the lid has a hinged compartment. The main area has a wooden lift out lid and a lift out tray. 

Not in perfect condition- some nicks and splits (see photos) but still sound and solid and not a million miles from being perfect, with a little TLC!
