Cyberman Blue Chest & Gun Arm Shortpacked Series 7 Cyberman Action Figure with Blue Chest & Gun Arm. As seen in Nightmare in Silver (2013)
The standard release Series 7 Cyberman has neither the blue chest detail nor the gun arm. The blue chest variant is less common, exact overall quantities unknown, though minimum 100 pieces per release wave.
There exist a small, unknown quantity of 3.75" Cyberman with Gun Arm but no Blue Chest detail. Allegedly once referred to by Character's Al Dewar as 'a variant of a variant'.
In February 2015 this figure was released as part of Wave 4A in revised packaging replacing the Series 7 flash with 'Wave 4' and called 'Cyberman With Arm Gun'.
