Hi Michael. I was also bidding on the #36 pants. My guess based on the tag is Larry Brinson 77-79. GUU member both-teams-played-hard has an excellent Sand Knit tagging guide if you haven't already seen it.

Your other pair of pants is very intriguing. What's the tagging on that one?

Regarding, home vs away ... I believe they were one in the same up until 1981 when the navy jersey was introduced along with a true gray color for the pants.
