I was buying those in the early 90's. Just checked a can of Herco and artwork rev. is dated 4-90

I seem to recall using containers like that in the late '80s.

Near bottom of page.
Judging by the pictures, I would say from 1970's.
Mine have a transparent lid where the 1980s is pictured with a red lid.

I just reloaded 200 rds of .44 magnum yesterday with 1980's Hercules 2400. It works great!

All still fairly current (to me) and in use at my place.

 

[WilliamSussman]

Three classics right there!

Just finished the same bottle of bullseye. Dated 82. The cap crumbled so i had masking tape for a lid for a few years. At 3.5gr a load it goes along ways.
