HOLDEN - Arbeitswerkzeug Industrial

This Gardening or wine agriculture crop protection sprayer is made by the enterprise of GEBRÜDER HOLDEN in early 20th century between 1900 and 1930. It's made of messing, and hold together by rivets. It has a pump in the middle and contains a build on Manometer. The hose is of rubber and has the sprayer at its end. The other end is drilled on a winding on the bottom.A top of metal closes the liquid entry. It also has leather bands to wear this on the back for working. It's patina is looking used but not damaged. This is a left over from a friend's grandpa and was used on the wine mountains in Saxony-Anhalt near Freyburg and Naumburg. I decided not to clean but gently with a soft piece of cloth for the dust. So there are green colorings as visible on the fotos from the messing oxidating. The hose is old and as rubber is looking then scrumbled. All in Al it looks like it is even now able to work. For that I have to say I m not sure if there is something missing but fotos show detailed what is on the object.
