This is indeed an early blown perfume bottle by Bernard Stoner of Kangaroo Island, South Australia. The photos below show a somewhat later perfume bottle, which has a similar general shape and the same trailed collar. The artist has a
website, where it is seen that he spent 20 years blowing furnace glass before turning to lampwork.
The OP may have found her answer by another route, in which case this reply is for the record and the benefit of other members. (Speaking of records, this resolution is 7 years and 115 days after the original query. That is a new personal best for me.)
