hello Loius Not an easy piece to assess for origin or date, and probably nil chance of finding a maker.
You don't say whether the 5" includes the stopper, but in any event my thoughts are that this is too short for wine or similar, so we're looking possibly at a cologne bottle or some form of spirit/liqueur container.
I'd suggest this is an inexpensive mechanically mould blown piece, but your comment that it has eight mould seams is very unusual - three or four seams is usual, and sometimes only two. Unfortunately, your pix are too small and definition is lost when these are blown up.
Sometimes better quality pieces will have a number engraved on the stopper (often on the stub) with an identical number somewhere on the neck of the body (or even the base) - it's worth looking - although if this is a moulded piece then there may be nothing - I assume the decoration is moulded.
Very wide and shallow depressions under the base - with fairly narrow amount of flat area remaining - can be indication of early C19 date, but not a reliable method of assessment, and this piece might date anywhere from 1860 to 1920. Wear can be misleading, since utility items tend to experience more than prized pieces.
Could be from almost anywhere - but interesting piece - let's hope someone else has a better idea of its origins.
