Kind of useless to see so many views and no replies!

no replies typically indicates a "Nope, no one uses them" otherwise there'd be dozens of schematics, pics, and commentary

"Duodecar" sockets for Compactron tubes.

Ampeg used plenty of Compactron tubes.  Mostly, I steer clear of those models because some compactrons are inexpensive, but others are pricy & hard to find.

I have a plan to build an amp using compactron tubes in 12 pin
Just haven't got to it yet.
I would likely use sockets that can be mounted with screws or  rivets, yours look like press fits.
If you are trying to get rid of them why not list on ebay to see if you get any interest.
