I have seen this basic set in a number of places, including the now-defunct Hobby Boards and SparkFun. In the datasheet found on Sparkfun, it appears that the manufacturer is Argent Data. I see the wind and rain set on their website, but not the temperature shield/sensor. Their interface has "One Wire", which is probably used for the temperature. The other sensors seem to need direct connection to the interface, but I don't see connectors labelled for them.
From what I have seen, this set is mainly used for Arduino "home brew" kind of projects. I think that I have seen commercial display consoles using this set or something very similar, but I don't recall where.
For what it's worth, here is a link to the datasheet on the Argent web site:
https://www.argentdata.com/files/80422_datasheet.pdf. Here is the
main information page. In Argent's
interface box, I don't see the connections for the wind and rain sensors on the box connectors. There are connections for a APRS TNC that would be used with a Ham Radio 2meter radio, but it does have RS-232 for a PC connection.
This might be too much to get into for you. If someone knows who has a console/display that will work with these sensors, that is what you are probably looking for. Maybe that Zephyr unit in the previous post would work.
I just found this on Ambient Weather:
http://www.ambientweather.com/wswestrepaan4.html. (WS-1090 [discontinued] parts page shows a console for $48.99, no guarantee if it will actually work with this set, but it might be worth a try for the price)
On closer inspection, your photo does not seem to show the transmitter, and this WS-1090 was wireless. From what I can tell from the instructions, the wind/rain tie into this box:

might be inside the temperature shelter (round thing with plates).
