    Nice restoration.

    In case anyone else has one like this they want to restore, and at risk of being the safety police...

    With the passing of years and the collective amnesia that comes with it, it's worth remembering that these were used to spray all sorts of dangerous and toxic chemicals that are banned today for very good reason. I'm old enough to remember directly and my father who took over the farm is still alive to tell me. Most other viewers may not be.

    My grandfather (a farmer in this era) had one very similar to this device. I know for a fact it was used to spray DDT, Deildrin, Arsenic, and probably a lot of other things. Arsenic (in sufficient concentration) excepted, none of these are likely to kill you immediately; but you should be aware of what these devices were used for and take the appropriate safety measures.

    I don't want to discourage someone from restoring one, just be aware.
