recumbent bicycle photo archive

My U.S. production compnay is currently producing a show for The History Channel entitled Eureka. It's a program about modern-day inventors and their inventions.

The invention we are featuring is a recumbent tricycle that operates on pedal power as well as battery power.

We are looking for archival photos to help tell the history of recumbent bikes.

Does anyone have any ideas where I could get the following photos?
Recumbent bikes pre Charles Mochet
Portrait of Charles Mochet (or anything w/ Mochet in it)
Mochet's 4 wheeled velocars
Mochet's 2 whheled velocars

Can you point to a source that would be of assistance?
