5 speed breather

I've read about ensuring the gearbox (5 speed) breather is not blocked.
Can someone point out its location please.

During the conversation he said " make sure the gearbox has a breather by drilling a hole to the right and forward of the gearstick mounting plate". My Lotus box did not have a breather so I drilled and tapped the alloy cover and screwed in a small tube with 1/8 " internal hole and protruding say 20 mm high.
Without a breather the box when hot will expand the oil and more important the hot air inside the box will expand considerably and push oil out past the seals.I presume that Lotus rectified this with later produced boxes.

In the location mentioned might be a good idea. Should allow the box to breath but prevent any gear oil escaping with out messing bends and tubes.
Another thing for when I am swapping the chassis.
