There are a bunch of vintage tama fanatics at the link below who know everything there is to know about your drums:

I have a set of 83 Superstars in Super Mahogany.

It was sometime around 1980 that they discontinued the mufflers. The Mahogany ones are much less common than the Cherry Wine, (probably because Neil Peart played a monster Cherry Wine kit) so it'll be harder to find pieces to add to your kit.

Good luck

Welcome to the forum ! Those are some sought after, valuable, made in Japan, high end Tama drums. I had a set in natural maple finish, and they sounded superb. Very warm, punchy and bright with a nice low end.. Your kit looks like it's the super mahogany, and are in pristine condition judging from the pics. Tama has also reissued your exact snare drum..Very nice ! Here's a link to what you possibly have, and the Tama link to see your snare drum and it's 40th anniversary reissue.
