Anyone recognize this strange Witch Hunter Captain?

I just received a Mordheim Witch Hunter Captain from Ebay, but noticed his pose is wrong.
The normal one holds his right arm at his side, gripping a severed head by the hair. But this one holds his arm out in front of him. He came with a plastic crossbow bolt glued to the fist, but I don't know what was there originally. The arm is definitely a part of the main model, it's not removable. I tried an acetone bath to melt any glue but it's just as solid as the day it was made.

Anyone know what it is? Was it an alternate pose or something?

Thanks!

The description doesn't sound familiar, although it does sound cool. I'll have to wait for the photos...internet moves with the urgency of a glacier here also.  

As long as I'm at it, WELCOME ABOARD!. Have a FUN stay!

Thanks for the welcome, I had considered combining this with an introduction in the new user forum but figured it was better suited here.

It is the Witch Hunter with the head. It looks like the left forearm & his head were repositioned...the decapitated one is obviously gone.
You probably would have gotten more responses in the Painting & Modeling Section; that is THE place for miniature questions.  

Well I suppose that makes sense, I'll bend his arm back straight.
Thanks for the assist!
