Can anyone help figure out what parts the head and tentacles are made from in this conversion: http://crusadedude40k.blogspot.com/2013/01/killbotz-and-white-dark-scars.html

A triarch praetorians back. Dont know about the tentacles.

I'd say the tentacles are from one of the new Chaos MArine daemon engines. Most likely either the Forgefiend or the DV Hellbrute.

The tentacles appear to be from the Dark Eldar engine.
