NOTE: The winning percentages are for White, 40% is terrible for White and 49% is merely below average for White. BUT, this opening might be OK for OTB, maybe - possibly - perhaps. Then again, you didn't say you wanted to play it as White, maybe you just wanna know how to play against it. As for any insights into it you're going to have start playing over every game you can find with it, since it's probably not even a footnote in most opening manuals. Good luck!
I've played this OTB in a club championship a few years ago. My opponent was former South African chamion Albert Ponelis. He was so taken aback he declined the gambit, and I ended up messing up a winning position in the end :)

Rasmus pape has written a book on this opening "Gibbins-Weidenhagen Gambit", Schachverlag Manfred Madler, 1991.
Not very sound for white
There is nothing unsound with this opening. Of course people who play this without any knowledge will deform the statistics. Solid lines are 1.d4 Nf6 2.g4 Nxg4 3.e4 d6 4.Bg5 (or 4.Be2) and 1.d4 Nf6 2.g4 Nxg4 3.e4 d5 4.Be2
Also GM B. Larsen find nothing wrong with this opening ("Skarpe abninger", 1983, page 49)
It's a shock weapon for surprise. The key for White is not to expect or play for immediate compensation - just take the tempo and figure the open file will come into play at some point. Black can easily withstand any direct attack, and often gets a killer counterattack, but if White plays slowly and develops and improves his position, he can get chances later that aren't evident in the opening.
But don't figure to use it often. In any group, word spreads fast, and players who are not surprised will be ready to just try to cash in the pawn.
I am sure you never played this opening. You give comments about something you dont understand.
