I read that LP's sometimes had zinc tailpieces that weighed around 78-90 grams instead of the ~29-38 grams that the aluminum ones did, and sounded very bright and harsh compared to the aluminum ones (relative)
but what about the bridge? I heard some say it's a very special aluminum alloy, others say it's zinc...
and did the tailpieces also use this special aluminum alloy if it was a thing?

Maybe the moderators can move it?

I could be wrong, but it is my understanding that the bridges were ZAMAK (a zinc alloy including elements of aluminium, magnesium, and copper) with rather flat brass saddles. The thumbwheels and posts are brass, the tailpiece is aluminum and the studs and bushings steel. What composition each metal has, no idea but it properly makes some difference too.

Yes, the bridges were Zamac and they affect the sound. Personally, I prefer the later "monkey metal" stop bars over aluminum.
