Haven't even cleaned this bottle up, yet, just found yesterday with a couple others. I'm not sure what this one held or from when but looking at all the posts and photos here, I see nothing like it. Maybe someone can shed some light for me and I will most definitely be getting more and have questions in near future. This bottle is 9" tall, has a base of 3 1/2" and a mouth of 5/8". Stippling at top half under neck and at the foot, has line w/ arrow in top section as 32 fl oz mark and says duraglas in foot stippled section. On the bottom it appears to be a 6 ( could possibly be a G ) then <I> 1 with a 7 centered underneath the diamond shape. It is in perfect but dirty condition and has no lid or label, what can you tell me about it; including it's value or if anyone would be interested in it
