chord question

Hey all,

Abusing you guys, got another quick question again. Googled it for a bit and not finding the answer.
There is a Czerny etude I am learning. There is 1 chord I did not manage to identify. Not sure if it is a good idea or not, but it is a lot of notes so I am marking the chord name (basically cheating) with a pencil so I can read it faster. If I knew what chord it is, could read up a bit on it and this would also help me learning chords.

It looks like BFG, or GBF (I'd assume the first is an inversion of the second one).

I tried to google / wiki etc. some stuff up but I'm not getting any smarter. The closest I got is the G7 (dominanth 7th) with GBDF, but I'm not sure if this is the same if you just use the GBF without the D.
So I just want to know what that GBF is, and how it is marked.

thanks

In the two circles.

It's just a dominant chord, a G7 without the 5th (D)...
