Coffin flask - pint

This Chase Valley Glass Company Factory 1 pint size flask in a beautiful shade of green is embossed on the bottom "C.V. No. 1 MILW." It is crudely made with bubbles and irregularities in the glass. There is wide variation in color among the factory 1 flasks. In fact it seems hard to find two that are exactly alike in color. The lip is applied.
