Enamelware Metal Air Pot - Auto Dispenser - Retro Drink Dispenser 
 
 
Picnic drinks dispenser.

It stands 33cm tall. It has base measurements of 23.8cm x 12.4cm.  The lockable push buttons have a diameter of 10.5cm.
 
It works without leaks. 
 
The capacity isn't marked on it.
 
The body is enamelware metal, and the lid, handle and base are plastic. 

It is in good vintage condition. The background is all one white colour. The photos have some shadow artefacts.
 
I don't know if it will keep hot drinks hot and cold drinks cold but it is certainly useful for taking two drinks on a picnic where longterm temperature is not a consideration.
 
It does not have any brand name details.
