Miniature Threshing Machine

 
We went into Cambridge and while my husband had brunch, I had gluten-free scones, butter, jam and cream at Harriet’s Tea Rooms before going to a Mensa meeting on the other side of town. After the meeting we walked around Parker’s Piece as there was an event taking place; it continues on Sunday.
 
Today’s picture is of Miniature threshing machine; I am old enough to have seen a full sized one working, although I do not recall a ”Bisto” tin underneath!!
