Went through my box of orcy goodness today and came across a few I haven't been able to check off in any catalogues...
Left guy looks like
fella #4 from Notlob's - got the same body and spear, but one arm and head differs. Not much of a mystery really.
Middle guy is a complete mystery though... No idea where he's from, but I feel safe in assuming it's a Perrys sculpt. Right? =)
Right guy is also a bit of a no-brainer, he's pretty much like the other orc shamen from that era. Not in any catalogue, so wondering if he's from a special set or something.
