Hi speakerdave, thanks for saving the images here. Since this driver uses the threaded coupling to the horn it would be a Lansing 284 or 285 driver, not 287 which used the three bolt mount like a 288.

I have a pair of LU-1011 drivers and they are model 285, with 20 section radial slit phasing plug. Most likely this one is also.

Edit: on second thought, this driver has the die cast rear cover with the screw "ears." I think this cover began with the introduction of the 284B driver, which was Lansing's return to the circumferential phasing plug after a couple of years of using the radial slit plug in the 285 driver. So, the auction driver may be a 284B with circumferential (concentric slit) plug.

Ah--thanks for the correction. I cut-and-pasted the auction title. Unfortunately I cannot edit the thread title here.
