Margi:
I think you're referring to the label in Gallery like yours that goes with a Galliano Ferro label. It's definitely Murano. Yours is different, being that it looks like paper with a different bottom. I presume it's an early version of Svazzo's label. I've wondered if it were an early version of the Promovetro label. Yours has an "AC" on the left, while Svazzo's has "AF." The different letters would stand for different companies.
I would guess 70's /early 80's for yours, the label that is.
