Here's mine. Unbranded thing bought off eBay, less than £50 complete with boss.
Diameter is 315mm (outside) but the bottom is 'squashed' by about 15mm which is useful as being 6 ft 3 I need all the room I can get. Think the original Nardi was 350mm.
ETA - see next post for a photo of the Nardi.

What's that thing above your stereo, snotrag? Some sort of elaborate shift light?
Air fuel ratio, home made from a kit. The panel in the pic is temporary, I'm getting another Stainless one made up like the old one - 
to house that display, an on/off toggle switch for it, and a vacuum gauge. Something to keep me occupied and its actually interesting to see how the ECU is operating in different situations. To be honest the main reason I built it was something to do, and to re-learn soldering and wiring etc. Takes a feed from the lambda probe, and from that determines what the ECU is doing with the mixture. Its not as accurate as a wideband (around the middle ground) but it shows lean/rich very cleanly. It works, as you can see the revs changing at idle as the mixture changes and feel it self-adjusting.
It also highlights the reason why there so crap on fuel - it goes to full rich very easily above 4krpm, and the speed of closed loop cycling is very, very slow, less than 1hz. I was really surprised at that! Its a proper basic ECU, so its no wonder that a home-built megasquirt, with no other mods other than ditching the AFM for a MAP sensor is supposed to release another 20+bhp easily. I'm very tempted to build one - again, just as a 'why the hell not'.
The downside being that after I've done that, it will be positively begging for a cheap turbo+manifold or a Mini-charger!

How did you build it? Are there any instructions anywhere? I'm guessing it's more difficult than it sounds!

Actually its a bit less impressive than you might think, its a PCB kit! Was a good little kit of practive soldering etc, bought myself a new iron and a little wiring/crimping kit, and I've done it as neatly as possible with a splice off the lambda signal wire through the bulkhead into the dash.This - http://autospeed.com.au/
is a fantastic website if you like tinkering, and they sell some kits too.
Read through all their tech stuff, theres loads of interesting things to do such as measuring where the high-presure areas are at the front of your car to design ram-air kits, and measuring air intake temps in different scenarios (ive also got a temp sensor in my intake tract, been measuring temps in different situations and with different cowls/shielding etc round my filter.
Its a website full of ideas for cheap-geekery.
