I could be wrong, but I am fairly certain that those L/R grills were changed to the current grills sometime during the rev 1 driver's lifespan. To my knowledge there were no driver changes before rev 1. I can't find the pair you mentioned on ebay. I googled LCD-1 to see if it looked anything like the LCD-2, as I was curious if the L/R grill was perhaps carried over from that model, and I found a surprisingly different looking headphone!
