JBL Gurus, could you take a look at this?

I picked this up in a lot of JBL gear. I was told it was a LE100S but it doesn't match the LE100S or any of the 175s I have. The cover bolts are closer to the edge (see pictures) and although a 175 the diaphragm fits, the screw holes to secure the diaphragm are on a larger diameter (like the 2482 is to the 2440). What the heck is it?

Thanks,

Eric M.

UPDATE:

Was just looking at the picture. I noticed there are 2 sets of mounting holes. I turned the diaphragm 180 degrees and it fits the second set of mounting holes. Still, some oddities about this one.
