Rarity & Significance
Common as a part of the original set, but highly prone to loss. It is a critical component for collectors seeking to complete a '100% Complete' G1 Optimus Prime or Ultra Magnus, which increases its individual demand on the secondary market.
Special Features
Features a 5mm-compatible peg base; designed to be used in conjunction with a black rubber hose (not pictured) within the trailer playset.
Notable Variations
There are minor mold variations between the 1984 Pre-Rub sign versions and later 1985/86 versions, primarily reflecting the crispness of the mold edges and the specific shade of gray plastic used (Optimus Prime's is typically a slightly darker or bluer gray compared to some Ultra Magnus releases).
