Yours headstamp isn't that old. (Depending on your definition of old.) I don't mean to devalue it. As the user was likely quite content with it. And it's old enough to save. I try to save an oldest after looking up unfamiliar ones. But end up not discarding as much as I might....
You can drive the primer out of it and screw it to something. Like a knob /handle. "high brass" works better but all will work.
Or make a button out of it.
Or use it for an inlay.
or a walking sticks handles butt cap.
Or a kind of a hook to hang something onto.
Or leave it as is.

16's had thier day.
For pheasants and more here in the midwest.
A bit tamer than a twelve gauge. And a payload study can spark good debate about efficiency.
1926 was not a good year for the 16 though. It got bumped out of the running for permitted skeet use. (See attached link to an article.)
Yes there were users not complaining in the fields hunting game. the 50's and 60's still saw 16's in play.
Outside of reloaders though , as the 16 fell out of use the ammo costs and availability had to factor.
Which in my opinion (worth a coffee or single round of 16 maybe) was a tough kick in the shins the 16 really didn't deserve.
I acquired one a while back I'm looking forward to trying.
The sweet 16 gauge shotgun is the most logical of all the gauges. Terry Weiland explains why has it fallen from popular use.
