3 input NAND using only 2 input gates and no NOT gate

3 input NAND gate function using only 2 input NAND gates and NO NOT gates. 
Quora question from several weeks ago - designed it on the fly, 3 quick attempts on paper and finally decided to prove it after a guy went to the effort of writing a Program in 'C' to test it - you obviously can't tell from my hand sketches it works so I've done this to add screenshots. One guy tried and failed - nobody else tried. To be honest I thought it'd be harder given the first guys efforts.

You joined a year ago and this is the first circuit you posted? I was like that until 2-3 weeks ago, when I decided to publish all my circuits, except that the majority of them were derived. Since then, I've been making/posting circuits like CRAZY!!! Why don't you post some of your circuits?

Because of Intellectual Property Rights :( I design for a large company designing electronics for Mass Spectrometers and there's very little I can reproduce unless it's something like above which I've done in my own time with my own 'tools'. Sad because I have many 'clever' circuits. Plus - I actually forgot I'd purchased it so after an update I forgot to restore the purchase and thought I was limited to 5 components - it was only when I went to buy it I realised I already had a professional Licence lol.
