In retrospect, I've been analyzing the landing gear system. I think the
fact that we didn't get the gear warning horn and the red gear warning
light was actually an indication that the gear was down.

Many retracts have multiple independent systems that sense gear position.
You may have to get a maintenance manual and look at the wiring diagrams
to figure it all out.

For example, my Comanche has 3 switches in series to light one bulb.
There is also an independent switch on the nose gear only that is used
as part of the gear warning horn (in conjunction with a mechanical
monstrosity behind the throttle). If the green light doesn't come on,
but the gear horn doesn't sound when you retard the throttle, the gear
is probably down (it's all mechanically interconnected). You can also
see (and feel) the emergency extension handle to know if the gear is
stuck at some point.
