It appears to be a quart in size. Is that correct? Or midget pint? Hard to tell with no size reference.
Not saying for sure, but this may be it. I checked back and forth between images and the molds appear to be the same. If yours is an authentic grass green midget pint, you could just about name your price.
Apparently Tony didn't like the answer he got on the Jars discussion page. So, instead of posting photos of the base & lip as requested there, he chose to post the same single photo here. I stand by my answer posted on the Jars discussion page.
