Perhaps someone wanted Campy Ergo and swapped in the slotted insert for 7-sp into the R Ergo shifter. Correct me if I'm wrong, but 7-sp Ergo doesn't ring any bells.
Given your list of bikes and previous posts, one wonders about a few things.
How about a pic of that 7-sp rear and that R Ergo 7-sp shifter?
Given the inconsistencies, something is amiss.
It may be 8 speed Ergo and they are not using the last click. As stated earlier, I think the Ergo is an upgrade as 7 speed Chorus would be correct for Miyata's 1990 custom package.
