Please forgive the following, but;

You really need to learn how to post links ( if not pictures ) directly within your posts ( ie; why make others do all the work to help you out? ).

So you know, the software running this site, allows direct "pasting" ( of a copied image file ) directly into the editors box ( when creating a post ) .

Now having done my "finger-wagging" (http://www.oxforddictionaries.com/definition/english/finger-wagging)for the day / your diaphragms do indeed look original to my eyes .

I believe the round stamp ( "SP" surrounded by a circle ) was a relatively new addition to JBL parts ( "relatively", means sometime within the last 40 years that I've been buying JBL Pro products ).

That's a ( minutiae of detail ) that I don't think anyone here can truly nail down ( closer to, + or -,5 years ) as to it's first appearance ( on replacement diaphragms ).

The application by the factory ( of the round stamp ) was ( in my experience ) not terribly consistent ( based on the OEM JBL diaphragms that I've purchased / starting in 1977 ) .

Ok, i thought it was a note for a not original dia. The driver must be from the 80s, perhaps the dias would never changed.
