Your bottle is Persian and is of a type that are generically referred to as 'Saddle Flasks'
They are notoriously difficult to date as similar production techniques were used from the c17th century through to modern copies.
Phil Culhane is probably acknowledged as the go to expert for these type of bottles but his web site appears to be down at the moment.
I think those amber ones are less common than the green ones. Still a lot of discussion revolving around this Persian glass. Too bad saddleflasks.com is down as Phil has been one of the rare collectors to show real interest in this form of glass.
