Triangular Green glass pitcher that seems older than most

Have not seen any thing like this pitcher before so would appreciate some help in id.

The glass is a medium green.

Looks free form as the rim at the top is smooth but not regular.

Lots of bubbles. Swirl ridge design on outside.

Triangular shape.

6 1/2" Tall

Triangular shape 3" x 3 3/4" x 3 3/4"

Attached Handle 4" tall

No branding or markings at all.
