XF 1.2 What version of xenForo is this?

I know this is a really random question...

But I really like this text box: ( http://s12.postimg.org/5wrcb36tp/chrome_2013_10_23_15_57_58_11.jpg )
Better then the newest one, and I was wondering what version of xenForo I would need to download to get this "older" styled text box.

Thanks for your time.
Thanks for the fast reply.
I also know that I can't downgrade. I have not officially restarted up my community again with XenForo yet. (I have 1.2) But I have disabled the site so non of my members could rejoin.

But thanks again Brogan :)
