Found in the shed of our new house.

Looks like this was originally a storage box for half or full pan Watercolour blocks.

There are still a couple of brushes inside and a ceramic Watercolour palette, seasponge and two pots .

Not sure if pots were originally part of this but palette fits nightly in so assuming this one did.

Box is not stamped with any maker

Only thing stamped is the ceramic palette which say Windsor and Newton.
