i didn't know this was even possible!
notice this is a Flyer Type XI clockwork shell, not the similar Type III electric (#3195), though with less metal, i cannot see why this wouldn't work with both types .... unless the headlight gets in the way. actually a good recycle of a locomotive that is often found with missing side rods or damaged/ missing wheels.
btw... this is a current eBay sale, so be aware it is not 100% Flyer as advertised.
cheers...gary
