A few months ago, "Cinnamon" broke an elbow, losing a forearm. So I started making modular replacements with Kotobukiya MSG Weapon units starting with the Gatling Gun and Dynamic Chainsaw but then I saw they released the Spiral Crusher.... So I got three.
I had to make some adjustments by replacing the polycap from the Spiral Crushers with ones from another Bandai kit that were a more compatible fit to the Beargguy's shoulder peg. I'm still working on this to improve the shoulder's motion range and also planning some paint work to make these two arms dedicated to Cinnamon.
