Birkin History Question

Bumping up, because I'm curious...the Birkin came out in 1984.
Did you ladies and gents who have been with this brand since
then, have to wait until 1990 or so to see the first Croc Birkin?
I could take a guess and say 1988?
 
I know that the first matte crocs came out around the late 1990s - year 1999 or 2000 something like that. I remember Hermes only had about 4 colors in the matte crocs and all are lined in cotton/linen. (rouge h, anthracite, havane and indigo blue)

If I work back, mid-to early 1990s sounds about the right time when H made birkins with crocs. But am leaning towards mid-90s ...
 
it has to be early 90´s (for the shiny croc) as i absolutely remember the strom bleu jean released.you know the color first appeared on shiny croc (where it looked real denim like) and only later became a non exotic color as it was a huge success.
