Series: Model Graphix Gundam WARS III: Gundam Sentinel MSV
This is the Zeta Plus C1 [BST]: "Hummingbird" in demonstration colors. Basically it is the Zeta Plus A1, but with both C1 (space use) upgrades and BST (booster) future grades. The C1 parts consist of fuel tanks on the wings and a smart beam gun directly attached to the shield.
The Hummingbird parts consist of high speed use upgrades. Boosters on the Arms and in place of the Lower Legs are very similar to those of the S-Gundam Bst or Ex-S (or Deep Striker) with a crucial difference. The boosters on the Hummingbird are modified to transform with the machine. For this, fuel tanks that are usually IN the booster housing are combined and instead placed under the torso, the pelvic area of which is also reinforced with a different armor plate. In their place are mechanical components allowing the boosters to rotate and leave space for transformation. The arm boosters are each equipped with a pair of cannons. The C1 shield -already equipped with the Smart Beam Gun- also has the S-Gundam smart beam gun attached as well (the black weapon). Though the machine can also equip the beam rifle that the A1 normally uses, I'm not actually sure that the dual smart beam guns can be fired accurately with one arm. I'm fairly certain it requires both arms to keep them steady.

Basically the point of this unit is to exercise hit and run tactics similarly employed by the Hazel-Rah though the firepower is substantial. However, this is a Mobile Suit Variation and it's never able to see combat in the story. If it had, the machine would be a mid-gray color like the C1.

A larger/wider/cleaner version of this image is supposed to be the index page in the ol art book. I cut it off a bit just to be a hassle
