This wonderful collection of switches, knobs, and gauges is the panel from a beautiful Stinson Reliant spotted at Oshkosh 2013. Observe that while the switches, radio, and wood are clearly all new, the owner has kept the gauges in what I assume is their original configuration.
I half wonder if a glass panel would look good in a classic aircraft like this. I suspect that there are as many opinions about that as there are pilots, but I think a modern glass panel could look really cool if it were retrofitted correctly. I envision the classical lines of an airplane from the golden days of aircraft aesthetics combined with the convenience of modern avionics.
