What breather is on this flatty?

I stole this pic from Paul's video of that bad sounding little T....man I want a cam!

I'm still trying to figure out a way to give my AV8 a breather on my 59AB. I've seen them bent, cut at an angle and some (Keith Tardel) even made a cool looking little offset. Well, I would like to keep it symetrical looking- I think that is what makes a flatty look so good.

So, does anyone know what this is?

 

****....just noticed, he's not running a fuel pump in the stock location......oh well, still curious...

 

Looks like a modified oil pan breather similar to this.

 

this is a specifically-designed unit for flatheads - see a lot of them here on west coast. I've never bothered to check what brand it is - sorry
