Looking for JBL 2121 Cone ID marking info

[SoCalBob]

Hi:
I found a pair of 2121 mids for a 4343 project I am starting, but contrary to the sellers claims, the cones look to be aftermarket. Can someone tell me if the original cones had any identifying marks on them, something similar to the '50320' marks on my 2231As?

Any help would be greatly appreciated.

Why don't you post the pics? I've 4343, with all parts original, but cones and surrounds of 2121s are a little different from each other.
