This is a long shot, but I know some of your are distinguished collectors of arts so lets try anyway.
Back in moot era there was a /tg/ drawfag that went by "chink" or "eccma417" he was making 40k memes - faptau, farseer macha and such. He might also have been involved with BroQuest before Shwig took over. Any idea where/how I could dig up his works besides what's preserved on r34 and his (long abandoned) DeviantArt?
