Not sure if this will be of any use, but this is a game I played as black in this gambit on IECC a few months back. White certainly didn't play too well, but it shows the sort of problems that white faces.

As you can see, I preferred to delay castling, it probably isn't strongest but it's another alternative.
Also, Tim Harding wrote a few Kibitzers on this gambit, not sure which numbers, but if you go to
www.chessopolis.com and to links and then openings, I believe there's a link directly to it, which saves having to rummage through the archives.
Hope some of this is of help,
Regards and festive greetings,
Craig
