Looks like this one except that it is sealed on one end and the caddies for the two drives have a cover plate that screws in over a gasket and rubber ring.
I got it in a shop in Hong Kong when I was there for a convention earlier this year. No idea if you can find it online, maybe somewhere like Alibaba.
Don’t fret. Discovering good music from before your own generation tends to happen in people’s 30’s and later. They start feeling detached from the “new” music, so start discovering music people from all generations loved and they will discover plenty of older music they then come to love.
Do have to say that the current gen especially is more detached from the music of their parents than Millenials and older were, because often they had internet and their own phones on which they listened to their own music, rather than growing up often hearing their parents music.
My mom was in a rock cover band that covered the 60’s-80’s and my dad was in both a brass band and orchestra, through them I got in touch with classic rock and the roots of metal pretty early on and learned my fair share of classical music.
My sisters kids have no clue about any music but what they share with their peers.
