With regards to durene jerseys, here are a few that are in my collection or that I've seen first-hand in other collections that are not Sand Knit. Note that MacGregor was not associated with Sand Knit until the 1980s:

1950s Philadelphia Eagles - MacGregor
Mid-1950s Washington Redskins - Powers
Late-1950s Detroit Lions - Rawlings
Late-1950s/early '60s Baltimore Colts - MacGregor
1960s Chicago Bears - King O'Shea
1960s Dallas Cowboys - Southland
1967 Atlanta Falcons black jersey (1-year style with white Falcon sleeve logos) - Rawlings
Late-1960s St. Louis Cardinals - Russell Southern
Early-1970s Chicago Bears - Wilson
Early-1970s San Francisco 49ers - Wilson
Early-1970s Detroit Lions - Wilson (Lions switched to Wilson only on their white durene jerseys circa 1971 as they continued to wear Sand Knit in their blue durenes)

Most teams started wearing mesh jerseys by the early 1970s although many teams would occasionally wear durenes in cold-weather games. Sand Knit remained the dominant supplier in the 1970s, but Russell became more active and became the supplier of teams such as Atlanta, Philadelphia, Kansas City, and Miami. Wilson was the supplier of a few teams such as San Francisco and Chicago during the decade.

Also of note is that in addition to the manufacturer's tag, some of the older jerseys carry the tag of the local sporting goods store that supplied the team.

Hope this information is helpful.
