The picture above has a 2440 on the left, a 2441 diaphragm on the right.

I think the 2441 on the right was manufactured in the early 1980's.
I don't know JBL manufacturing codes, so can't help you there, but I know these are real JBL product.

The 2441 has a black dot in the center on the other side.
IIRC, the very first 2441s did not have the dot, which was added for a little center mass and continued as a feature.

This 2441 has a number 61780 and 58747.
