Just brewed this bad boy. Ended up using Wyeast English Ale II instead of Nottingham. Had pretty awful efficiency (~60%), but it attenuated out nice and dry (1.008), so it still came in around 5.2% ABV.
Primaried it for 3 weeks, and it's been in the keg for 1 week so far (still could use a little longer, but already very quaffable!). Mine's a bit cloudier than yours.
I don't see this one lasting very long.
