.......... and all scratch built by a lady at work!
I like scenery as you may know and my new job gave me the opportunity to have this made from scratch by fellow security officer Mandy (former railway modeller) and what a lovely piece of kit it turned out to be............
...........15mm GZG figure and Peter Pig vehicle to show scale and painted by myself, there is a brief description of what a nodding donkey is below the pictures but they have been seen all around the world and in many a movie!
She may be tempted to make more........

A Pumpjack (also called donkey pumper, nodding donkey, pumping unit, horsehead pump, rocking horse, beam pump, dinosaur,sucker rod pump (SRP), grasshopper pump, Big Texan, thirsty bird, or jack pump) is the overground drive for a reciprocating piston pump in an oil well.
It is used to mechanically lift liquid out of the well if there is not enough bottom hole pressure for the liquid to flow all the way to the surface. The arrangement is commonly used for onshore wells producing little oil. Pumpjacks are common in oil-rich areas.
Depending on the size of the pump, it generally produces 5 to 40 litres of liquid at each stroke. Often this is an emulsion of crude oil and water. Pump size is also determined by the depth and weight of the oil to remove, with deeper extraction requiring more power to move the increased weight of the discharge column (discharge head).
