Here are a few examples.
Also, here is a copy/paste from a post I made on the subject last year:
From what I know, the first Duncan humbuckers (very late '70s through early '80s) had no logo at all pressed into the bottom of the metal baseplate (so it is a totally plain baseplate). The typeface/font on the sticker is sort of crude looking (like a typewriter did it, as opposed to a computer/laser printer), with no winder initial as the last character.
Starting somewhere in the mid '80s (I'm guessing possibly around the '83 or '84 time frame? I'm not 100% sure of the dates - I'd really love to nail this down - but I'm pretty sure we're talking '85 at the latest), there was a "large" "Seymour Duncan Pickups" logo (the big "S" itself is about 3/4 inch by 1/2 inch) pressed into the bottom of the metal baseplate (but does *not* say "Made in America" under that), sticker has the crude typeface/font where usually none of the letters line up precisely, last character on sticker represents winder's initial. Regarding *humbuckers* in this specific era (with these exact physical characteristics), I have seen "J" (who is confirmed as Maricela Juarez, also known as MJ), and I have also seen "L" (possibly Lidia Daniel, according question #131 on Seymour's Q&A on the Seymour Duncan webpage). Anyone seen any other initials on humbuckers with these exact characteristics (other than J or L)? One other characteristic worth mentioning that I have noticed is that the corners/edges of the black tape surrounding the coils/bobbins always overlap onto the bottom of the baseplate. I have several examples of Alnico II Pro humbuckers from this era, and the sticker (which seems to be always placed right over the Duncan logo) has slightly rounded corners and measures around 1 1/4 inches by about 3/8 of an inch, and the paper is slightly darkened to the color of masking tape (as opposed to pure, bright white). Also, the Alnico II Pro humbuckers I own from this era have the vintage-style braided-shield leads, as opposed to the 4-conductor wire which I believe came later.
Finally, starting somewhere in the later '80s (again, I'd like to nail this down, but I'm thinking possibly somewhere in the '86 or '87 time frame?), one of the most obvious changes is that there was a "small" Seymour Duncan logo pressed into the bottom of the metal baseplate with "Made In America" right under that, sticker still has the crude typeface/font where usually none of the letters line up precisely, last character on sticker represents winder's initial.
