Vintage Sculpture - Man and Woman Field Workers

I picked this up at a collector's house who recently passed. The family was so great and many of the pieces I picked up I can identify, but for this one I am at a loss...

The woman is holding resembles a fieldworkers canteen,
sometimes called a shoulder canteen, as it would fit up the arm and onto the shoulder, allowing both hands to be free to work. The piece is ceramic
pottery, you can see the glazing that is showing slight stress .
