I have it. It took me some months to get all the parts as it's not that easy here in Europe. First I bought the middle section. As the standard lid is not fitting it, I had to find the original one. Thnx to @vwengguy who found a complete WSM with a spare lid, I was able to convince the seller to sell me only the lid. I had also an issue with the door. As I was not going to pay the full amount for a new one by Weber, I eventually found one with broken latch which I was able to repair. Finally I found a SS food mixing bowl which was (I though it was...) fitting the lips for water pan. I was wrong. I had to find a solution for that as the bowl was literally 1/4 inch too small. The solution was SS clothes pegs which are now keeping the bowl from falling. Oh, I forgot one more thing - the charcoal ring. As I was also not going to pay the full price by Weber I figured out a solution which was a SS cake cutting ring[emoji23]. It's very thin but working really perfect.
So, having all this done I have now a very nice piece of equipment for the camping. I take also the standard lid with me and I have there always both - smoker and BBQ.
Btw - yesterday I added few extras: SS sweepers, ash bucket as well as a different temp gauge. I will give a try to the new setup today.
