Hi. You are struggling to see any wear on the base because it is not a very good picture for that purpose. Additionally, you are not looking at the base from 1" away with a x10 eyeglass.
When I say antique/vintage, I say with over 30 years of experience of buying and selling glass, having sold many thousands of pieces, mainly 1840 to 1940. (I do not exaggerate as I sold much to trade for high turnover). I have viewed handled even more.
Antique will now bring us up to 1922 and for the purposes of this bottle I am using vintage to be pre 1940 as a dateline.
It does not matter what description did or did not come with a purchase. I have many examples of very, very high profit margins I made where the description I bought it as did not match the correct description. My all time two highest profit margins were from other fulltime glass dealers who has mis described the item. I also in the past, have mis-described items and thus undersold, to other glass dealers.
If this were Murano, it would be the first piece of Murano glass you have ever seen with a star cut base.
Yes I do have knowledge of Ink Bottles by Whitefriars, Vasart and Richardsons, presumably you do not.
