Gen1 and Gen2 Hybrid should have the same height on the nose piece. The only difference should be the etching as far as I know. If it doesn't have etching it's not Gen2 unless it wore off or something. The Mumbo (pre-Gen1) lens is supposed to look "lower cut" because the cut on the nose piece extends further down due to the bigger razor blade nose.
The nose cut on the Black Rain frame looks like a low Mumbo cut that you would see for 67 and V. Are you sure that's a Hybrid? It's hard to tell from the blur in the 1st pic.
Taking a pic from Dann, if he doesn't mind, for Gen1/Gen2 Hybrid (Gen1 shown) the nose piece should be high up as seen below (The Mumbo lens would be a couple/few mm's lower):
