Differences between . . .|Winchester Shotguns|Forum|Winchester Collector

Jim F in CT said
. . . .”Trench Gun” . . . .”Brush Gun” . . . . “Riot Gun”.
My limited knowledge of these terms is . . .
Only the “trench” (and MAYBE the “riot”) have provision for bayonet.
The “brush” has no bayonet provision. (Nor a handguard?)
Do I have this correct?
Thanks!
  

As it applies to the Model 1897;

1. Brush Gun – 26″ CYL bore barrel, 4-round magazine.

2. Riot Gun – 20″ CYL bore barrel, 5-round magazine, no provision for heat shield or bayonet.

3. Trench Gun – 20″ CYL bore barrel, 5-round magazine, ventilated heat shield with bayonet lug.
