Wanted - broken Speedlite or lens

Hello! For my upcoming book I’m looking for a broken Canon Speedlite and lens. I’d prefer them to be broken since I intend to dismantle them and photograph their gory insides, but if you feel like generously contributing a working one, that’d be fine too.

The details: I need a Speedlite with a zoom motor mechanism, such as any EZ or 400 series EX or 500 series EX. As for the lens, I need one with a distance encoder, so most ring USM lenses would work. Or most recent lenses, including EF-S lenses.

Thanks!
