I dunno about the second one, but for the first, do you mean Miyata? The diamond cut-outs were on a few early 1980s Miyata built frames I have seen. The seatstay caps are also Miyata-esque. I'd suggest you look for your match to either a miyata or a univega.
I am not convinced that the fork is original. The chrome seems out of place for a miyata built frame.
