Thanks all!
Ron,
The lip is more flared than any other I have - the only one I have that is close is a Clarke and White quart, with a similar lip. Speaking of Clarke and White - a while back I told someone on this forum that I didn't think a particular pint had an emerald green variant - and then I found one that is definitely emerald green, and with a lop-sided top. I couldn't find the old post to correct myself - here are the pics...
This one shows the top a bit better..
Tucker's book says some of the olive green bottles are very emerald in shade - but I don't see any olive green in mine.
