Right, first things first sorry that this is another
TWC post, buts its aim is to permanantly rid us of them. Its about time we had a sticky for this subject... not a week goes by when someone asks what the options are and it can get a bit much. So,
moderator... please make this a sticky.
That said, down to business - Here are the ones i know feel free to add your own ideas too.
FTL
Paulson Games
Also sold separatly. Each wolf is a 6 part resin model, comes unpainted and unassembled. Resin calvary bases and saddles with armored leg sets are included (not currently pictured) Monsterous riding wolf may be built without the saddle if desired. Does not include a full rider, only the rider legs are included so you will need to add the upper body from your favorite line of miniatures.
