According to Schwing, the model 21 Salesman Demonstration Sample has a short butt stock and barrels to the end of the fore arm. The right barrel is cut out to enable the viewer to look into the chamber and see the breech. The eBay item is missing quite a bit, if, it was once a salesman demo sample.

That makes sense to me. Also note that there's no latching mechanism with the included forearm to allow it's attachment to the barrels.
Update: Someone has bought it for $510 so there was certainly no last minute bidders frenzy.
