Old green bottle with ring

Found this bottle yesterday, it's heavy and thick. Anybody know the makers etc. Has many tiny bubbles in glass.

Thank You, Billy

Just found it, a Chinese beer bottle with ring neck. Not much value, only around $25.oo

Thanks for returning to post this info Billy - I would be curious to know how old this might be.

The air bubbles suggest some age but I have no familiarity with Chinese glass manufacture.
