Not too long ago Shimano offered their hubs with a 'silent clutch'
mechanism. You may have one of those hubs. Another possibility
is that a prior owner may have added grease to the hub and that
will make the hub very quiet.

I like. How common are these hubs, and how do they stand up to the
abuse? Anyone know?

they are a bit hard to get your hands on
shimano does not sell them except as OEM equipment for the police only
bikes, almost every rea; police bike i have ever seen has a shimano
"SBD" (silent but deadly) freewheel

So that means I got really lucky?
I can roll up behind someone and they don't know I'm there unless I bump
them in the rear with my tire.
Stealth bikes?

Moderately lucky, or very lucky if you like it. I think the ultimate
knock on the silent clutch was that the design was a bit heavier and
pricier than noisier options. There is a cult following for them; I
think trials riders may be fond of their near-instant engagement.

I don't know how they hold up, but this type of clutch has large
radial forces that make it less practical in bicycle drive, where
space for thick reliable walls is hard to find. I think that is why
we don't see them in use.

On that line:

Really lucky I think. A friend was giving up on keeping a lot of old
bikes and parts and just gave me the wheel with the silent rear.
I thank his wife for making him clean out the garage.
