I have my old screen to that got baked. I've had it between some books to hopefully flatten it out. But I think the mortar screen is still good but would soak in some bleach.
To let you know as well, in case you didn't see my post on it, I spliced in some 14/2 wiring to extend the length of the led power supply placement to the ATS.
I have it all boxed up now and if you still want it you can PM me. Used the same box the L8 came in with fragile stickers plastered all over it .
I think its all there. Even have the spare orings still that I didn't use.
