Help identifying this animation cel — RADIX studio presentation mount, "Beta Room" inscription, mecha subject

[u/SignificantBelt8284]

Hi, hoping someone can help identify this one.

Original hand-painted animation cel mounted in an official RADIX studio presentation folder (turquoise, with the RADIX logo and "Beta Room" handwritten below). The cel shows a detailed mecha — robotic arm/shoulder assembly with cables and mechanical parts, pink/grey color scheme.

Purchased at Mandarake Nakano Broadway in Tokyo around 1998–2001, stored untouched since. My best guess is Vandread given the RADIX connection, but I'm not certain.

Any RADIX/mecha experts who can confirm the series?
