Good call on Jackson. His 1977 card gives us a pretty good idea about Topps' shedule for when a trade was too late or not for them to catch in their next set. The M's drafted Jackson from the Yankees on November 5, 1976, and traded him to the Bucs on December 7. As you said, he appears as a Mariner in the 1977 set. So the Topps deadline must have been sometime between 11/5 and 12/7. Thanksgiving, maybe.
When I lived in the northwest for school, I ended up adopting the Mariners as my AL team. I discovered that the first stab at a franchise didn't work out. The Seattle Pilots moved to Milwaukee to replace the departed Braves. So I selected this 1969 Topps Pilots card of Wayne Comer because I liked his sneer. https://i.ebayimg.com/images/g/cY0AAOSwZilmf3GL/s-l1200.jpg
He learned that he died a couple of years ago, but I found out this on his Wiki page: In 1969, Comer's only full season in the majors, he led the Seattle Pilots in runs scored, led the American League in double plays turned as an outfielder, and ranked second in the American League in assists from the outfield. He was also a member of the 1968 Detroit Tigers and compiled a perfect 1.000 postseason batting average with a pinch-hit single off Joe Hoerner in his only at bat in Game 3 of the 1968 World Series.
How about Mariners 1977 card for Grant Jackson who never pitched for Seattle and was traded to Pirates where he won a World Series in 1979.

He made the most of his big moments! Thanks for the interesting back story.
