Made by PenWal Models for Pratt and Whitney, depicting a notional
X-30 hypersonic research vehicle. The X-30 was proposed as a technology demonstrator for the National Aerospace Plane ("NASP").
PenWal was located in southern California, founded by Jerry Pennington (from Pacific Miniatures) and Walt Hyatt (Topping Models'
sales rep for many years). The walnut base features a glossy black plexiglass upright, etched brass nameplate, and small
Pratt & Whitney eagle logo.
