Spec weight for an '87 312 is 24.8 pounds per Miyata's catalog ( doesn't specify which size that applies to, and that's probably not the "Competition" trim of the 312, although I cannot find what precisely that entails ). I weighed mine at 24.2, with non-original tires ( and probably tubes ).

I'm pretty sure I could get this under 20 pounds, if I was so inclined. I really don't need two chainrings, and I never use the small one anyway, so I might make my own narrow-wide 50t and drop the front derailleur and cabling. There's also about a 1/2 pound that could be lost in the saddle and seat post -- the latter of which is an absolute tank. But for now, I like it the way/weigh it is.
