Not to worry - this could be a Clevenger reproduction (sorry to say it is not an original) and dates to the mid 20th century... Clevenger marks vary and some of their bottles are unmarked.
There were also other companies that reproduced this bottle, all with minor mold variations.
It does appear the lip/mouth is applied - and this does make a difference - since these tend to be the earlier of the repros.. You will find similar examples to yours selling in the $20-60 range.
