You're absolutely right, That's been some things i've discovered recently but forgot to update the post.

The crank is definitely triomphe
Brakes are likely Chorus from the dashes on the lever itself
Shifters are probably record but i find it weird that most else is chorus
Rear derailleur looks like Chorus
Front Derailleur looks a lot like Chorus to me as well. As with chorus and record from that era, there are lots of similarities
Hubs I believe are chorus as well
