Hmmm... looks exactly like my 6090 from WK Laser, except for the color. I wonder who really makes these. Regardless, you are going to love it!
Here's a tip though, if you drill a series of holes in the front of the lid you will vastly improve the air flow and smoke removal. Mine came just like the picture you posted. This is what the WK 6090 lids look like now and hopefully your lid will have these slots. You should ask them because it is a PIA to hand drill an equivalent amount of holes. It does make a difference though.
Hope the wait goes fast for you, that's the worst part of the purchase. lol
