Hi there, and welcome to the board! There are plenty people who can help with pressed glass here: Ivo, Bernard, Glen, Pamela, Dave, Mike, Sid, Leni, Christine, Connie and Tony.
As to your set, I'm no expert but it looks like the tray doesn't match the decanter and glasses. I can't quite see the pattern - is it like this one (without the handle) 170101987249, or 290106983632, or is it a more knobbly wood-look effect? What's common to all of these is the shape, colour and band around the top. All of the patterns I'm thinking of are fairly common and Italian. Is this what Luigi Bormioli was doing in the 1970s, I wonder?
