In case you have never shopped for a head, let me recommend one of my favorites. After unhappy experiences with knock-offs, I always come back to the Bludgeon Head made by the oddly named Crime Sciences Inc. It does the basics. It’s (for me, anyway) reasonably priced at $445. And I sort of love the description in their catalog:
These innovative new forensic models can help train blood pattern analysis experts in your agency for improved crime scene re-enactments, and provide a means for crime scene reconstruction and analysis, courtroom presentations and reenactments. Available as gunshot head and bludgeon head.
BLUDGEON HEAD: is made of a proprietary formula of high strength casting plaster and a custom blend wax formula, creating a hollow shell which is filled with pig’s blood*. The Bludgeon Head comes with a plaster base & head and one wax “spatter” shell pre-filled with blood. Order multiple shells and your head can be used again and again. Available in both vertical and horizontal placement. Striking this model, you can obtain realistic blood patterns such as:
Cast-off pattern
Back spatter
Medium velocity impact spatter (MVIS)
