Winter SWATriplex-18 dual magazine shotgun

A prototype shotgun designed by John W. Winter in the 1970s for police and SWAT use.

The design was ahead of its time with its many novel features including dual magazine tubes' which allowed it to hold 18 shots of 12 gauge shotshells. Sadly no physical examples of it exist anymore, only 2 black and white photographs and some written notes of it.
