A replacement bomb rather than a repaint: a scuffed dark grey brick with a pale blue display counting down from 00:45, yellow keypad digits and a red ARM legend over the button.

The view model is 3236 polygons on 1420 vertices with two 512×512 skins, and the player and world models are 1448 each, so the planted bomb matches the one in hand. The animations are the stock ones; the hand texture comes from Teh Snake.
