250 ml flask for sale, brand-new and used.

This is for a single vintage original Pyrex (Corning) brand glass round bottom side arm distillation flask from the 1940s. This is 500 ml size. The reason I am somewhat sure of the age is that these items were in a box along with some micro burettes that had a piece of lab notebook paper wrapped around them and it was dated September 1941.
