Sadly unless a copy of the schedule sent to stations in 1985-86 emerges online (extremely unlikely) or it turns out Bob Boden or someone similar saved a copy and it turns up online (you'd be surprised), the full air schedules for the nighttime show are lost to time. Would love for that to no longer be the case.
Unless someone at the show or Fremantle goes digging into the archives, the best chance to work out a production order would be for Buzzr or one of the streaming channels to begin running the show. Most of Game Show Network's 1996-98 airings include a graphic that shows the tape month/year, so I can narrow down and block together any individual show of the roughly 75 I have by month - but that's about it.
Honestly, I should put out a list of what I have, and what I know of the order and why. We know explicity which show was N0011 (first taped show, N-001-1 for nighttime, week 1, show 1) because GSN aired it in a marathon and explicitly declared it such on air (and it was the 'reset episode' when their run of the Kennedy eps hit the end and cycled back). We also know which show is N0335 because it exists as a slated master. That's...about it. With respect to Rewindium, the user linked, anything else is a 'best guess', including which show is the last one taped, based on those graphics and the various cosmetic and personnel changes.
Aired out of production order just means that episodes aired out of production number sequence. One day in May 1986 could be N0335, the next N0324, etc. (Hypothetical example, not actual schedule). Much like the daytime show, the nighttime versions generally used production numbers sequentially as they reeled off episodes. The only difference was the nighttime show not airing them in that same order.
The first aired show in 'A' markets (satellite, primary tapes), for example, was a show taped in June 1985 with Most Expensive, One Away, and Pick a Pair (and the big door pan-across opening), while the first show taped was all the way back in March 1985 with Lucky Seven, Grocery Game, Danger Price and the classic audience pan-across, still "Sparkling with excitement").
Re: Daytime show slates: I have a slated master from 1998 (0812K) that is still TBA (as are all before), while the next one I have from early 2000 (1362K) lists the airdate (2/15). Seems reasonable the change happened somewhere in there.
