Which version of the daystate air wolf has the barrel shroud?

[msc]

There's a few models of the daystate air wolf. The MVT, MCT, CDT and the normal air wolf.

Which one has the barrel shroud? To limit the sound? Do they all have a barrel shroud? Even the oldest earliest models of the air wolf without the screen

Best i recall having had 2 AW's over the years .... They ALL used the thin barrel going into a shroud being shorter than the shroud itself.
