Someone is selling a frame locally and states that it's a Miyata 1000. However, it's been repainted, so is there anything I can be looking for to confirm one way or the other whether that's accurate? Here's a link to the listing with some photos:

Also, if it is indeed a Miyata 1000 frame, any ideas on what it will take to repair the fork steerer crack that the seller says "...can be repaired..."?

Thanks in advance!
