Delta Gundam Sierra MSN-001SR/WP Delta Gundam Sierra+Woodpecker Unit by Dree
From the modeler…
The main idea is once again from Eday’s Arios take off, but I tried to make the UC version of it. The main unit is HGUC Gundam Delta Kai with some modifications, and the Support booster unit was built from HGUC Rezel type C. I named it “Woodpecker” because there was already “Hummingbird”.
