Hey, Guys. This is Larry "Fernandez" we're talking about.
IIRC I was even in J&M Hobbies when he was buying the roll of "Fox Semi-Gold" monokote by which he attempted to deceive his followers, (as evidenced by the seams/edges visible only when the engine is dismounted from the faux wood, plastic plaque to which it is semi-permanently attached with period appropriate, re-chewed, baseball card chewing gum).
Larry Fernandez, a modeler's modeler!

p.s. A little known fact: the engines Fleer gum stuck to the plaques are truly only facades overlaying an electric drive. (a dual triple AAA battery box is well hidden by camouflage monokote on the back of the plaque. So well done that most awardees are unaware of the subterfuge.)
