Very cool! Don't know much but google tells me the 2611 was the Deluxe 6 cyl 2 dr. Touring Sedan, 2611A was the Master.
The lower end 6 was the Master. The Deluxe had knee action independent front suspension vs. the solid front axle on the Master series.
The Deluxe had translucent dash knobs, black bakelite on the Master among other Deluxe "upgrades",
The Paint Code 16 is Black. Pontiac had 14 other standard colors in 1936, not sure if they were added cost but Black seems to have been all the rage during the Depression!
Trim Code 30 was Taupe Plush.
Found this which has a lot of extra info.
