Kadel Engineering Liquid Helium Dewar 5-Feet Tall

  

Kadel Engineering liquid helium dewar, from a university, this is 5 feet tall and 2 feet outside diameter, looks in pretty good shape, the last photo shows where one part is very slightly pushed in, the fittings look good. This is the type that has a liquid nitrogen jacket around the core helium part. Used to reduce the temperature differential with the primary helium dewar. Unfortunately the model number looks like it got destroyed and the serial number probably just faded out. This is a large, heavy, item.
