Having the Fresnel in front of the GG is NOT a strange setup. That's the arrangement used on hundreds of thousands of Speed and Crown Graphics. The reason is simple: The Fresnel (actually a Kodak product called an Ektalite Field Lens) is relatively soft plastic, and placing it behind the GG would expose it to the trauma of focusing loupes and other evil instruments and dirty fingers. It is the same problem that requires Beatie and Maxwell screens to have a thin piece of clear glass behind them for protection.
