TOOLING AND ASSEMBLY

---

The Numb Skull (Casting #6024) is a hallmark of the 1972 Zowee line, engineered with a 1:125 micro-scale footprint. Unlike traditional Hot Wheels, the tooling utilizes a multi-part snap-fit assembly requiring no metal rivets.

• Body: High-impact injection molded plastic shaped as a stylized human skull.
• Chassis: Black plastic lower plate that snaps into the upper body, housing the axle channels.
• Wheels: Proprietary Zowee-scale thin-axle wheels with black "button" hubs.

VARIATIONS: SHELL VS. RETAIL

---

Numb Skull is categorized as one of the "Original Eight" Zowee models released in 1972.

• Shell Oil Promotional: Distributed in clear heat-sealed polybags as part of gas station promotions. These were typically "raw" or had specific sticker sheets included for consumer application.
• Retail Release: Sold on individual blister cards at a traditional retail price point. Retail versions are identical in mold to Shell versions but are significantly rarer to find in the original packaging.

Note: No structural casting variations exist between the promotional and retail releases.
COLOR REGISTRY

---

Following strict historical documentation:

• Body Color: White (Matte to Semi-Gloss plastic).
• Interior/Details: Black (provided by the chassis floor visible through eye sockets).
• Information Not Available: No other documented production body colors exist.

INTERNATIONAL BRANDING

---

Outside of the primary United States market, the Zowee line, including Numb Skull, was marketed under different monikers to suit regional branding:

• Germany/Europe: Branded as "Western Willy".
• United Kingdom: Distributed under the "Fun-Buggies" label.

Note: The physical casting remains unchanged across these international releases.
CONDITION KILLERS

---

Collectors should inspect for the following common defects specific to this casting:

• UV Yellowing: The white plastic is highly susceptible to "nicotine" or "sun-fade" yellowing, significantly reducing value.
• Sticker Degradation: The adhesive on the "eye" and "crossbones" stickers often dries out, leading to peeling or total loss.
• Axle Warp: The 1:125 scale axles are extremely thin plastic; they are prone to bending under even slight pressure.
