We bought this at an auction just thinking it was beautiful. When we got it home and really looked at it we thought it was probably older than we had originally thought. We have searched and searched to find out information on it. The bottle is around 14" tall and around 8 and 1/2" diameter at its widest part. It has a pontil mark. I would describe it as spiral optic twisting around to the neck. There are no mold marks and the top is slightly mis-shapen. I have included two photos. Any help would be appreciated. Thanks in advance
