Hello, this is my first post here, so please excuse any ignorance. I've done a fair bit of research on the forum and the official SD page, but I'm still having trouble dating a pair of SH-4s labled with a JBJ label.
So, obviously the model, per https://www.seymourduncan.com/faqs/labels-built-before-2002, is SH-4 JB, wound by Maricella Juarez. Figured that much out from the linked page. At the very bottom it states that if the last letter on the label is J, it also says 83', but I'm having a tough time beliving these were wound in 1983... Any way I can get closer to the production year, since there is no serial number on either pickup.
I've attached a picture of one of said pickups.


Thanks in advance.
