Search the SoA archive forum, use Dundee's member number (2016), and use the keyword 'solo' . There are a few threads about Leonardo, but as near as I can tell he was first mentioned here:

But it dosent have the info you want. The SoA victory thread:
http://www.ironworksforum.com/ubb/no...=011430#000000
dosent help much either. There are a few more mentions, but if the proficiency points are given anywhere I cant find them.
