Coaster brake question...

The LBS I used to work at was overhauling a 50yr old Huffy and it had a very unusual coaster brake. The brake didn't work well so when I took it apart it had "clutch pack" in it instead of the usual steel pads, similar to an automatic transmission in a car or a wet clutch in a motorcycle transmission. This hub seemed to be very high quality compared to today's cheap hubs but it was just worn out and, of course no parts were available for it so I cleaned, relubed and put it back together.

Anybody know about these? This one might be a good choice if you can find an old one that's NOS or just lightly worn.
