It’s a 4 track...
Extremely rare.
I've got one. When I was remodeling the house, I sealed it in a plastic bag, along with a 4-to-8 adapter and some 4-track tapes, and put it in a wall behind new sheetrock. I've done that with other items. In the future, hopefully someone will be happy to find antique stuff. I have fond memories of playing 4-track tapes in my 1956 Chevy back in the 1960s. Memories only, because tape and rubber degrades making the device unusable. Same for the Titanic telegraph, good luck trying to operate it.
