I dunno, if You already know this little bit, but this sure looks gw-ish to me, there are parts from the Bretonian "Landsknecht" box, so this guy is probably Bretonian (or imperial), too.
I also suppose it's a conversion, because the hand on the hammer just do not fit exactly, like I would expect it from a complete mini (wether it's one piece or not).
so far - my 2ct

PS
googling hasn't broad any news to me (I'm curious now myself ^^), but since I could not find it on cmon regularly I cannot check if there are any infos there ... maybe a linked blog or something.
