I have them. I am the owner of the purple FM336 that you can find in previous pages of this thread and in reddit. I have done 600km with those wheels (G-One RS + Vittoria Airliners) They are indestructible so far. I have had a fall where I ate a tree that was laying on the ground and I didn't see, and the wheel ate like nothing. Spokes kept the tension and the rim has no damage. I have eaten potholes because I didn't see them while chatting with my ride-pal and nothing. They weight 1390+- GR, 30mm IW, 36mm EW, 50 mm deep.

It took one week and a half for delivery (Germany). Production time, I don't know. Maybe the setup you want is already in stock. You must contact them through WhatsApp to know further information.
