Vacuum Flask manufacturing in the 1950s

HF:  I’ve been contacted by a Chinese lady who is looking into her family history and their involvement in the manufacture of thermos/vacuum flasks.

This is my initial investigation into the business around the time her  family were involved, the 1950s.

Hopefully it will develop into something with greater order and substance.

Vacuum flasks, also known as Dewar flasks, Dewar bottles and Thermos flasks were invented by Sir James Dewar in 1892.

We need more information about the development of vacuum flasks (and enamelware).
