The pattern - or should I say the combined trio of patterns - was used by Dugan at his Indiana, PA plant, where it was made in Carnival Glass.
As I noted above, many of the Dugan moulds were obtained by L.G. Wright - but I am not aware of it being made by them in this trio combination. If they were to have made it (or more correctly, have had it made for them) they would have had to have the correct match of mould and plunger for these three patterns.
I agree with Connie - and although I do have the L G Wright book, I can't find the item in it.
On the evidence presented, it seems most likely that the maker of your item was Dugan. Beyond that it is impossible to say, based on the information that I have available.
