Hey Duke, do you still have the one I sent you that was very similar to this one? Was there a date code on that one?
Brian
Yes, I still have it. I just checked it and that one didn't have a date code. I think it's just a little older than this one. Danny, I think Chad might be right that it was the first year they started adding a letter on them.
I'm not sure most people notice, but on the older design the bottom was just round like this one and then weber removed the inner tabs that hold the top grate on and added a ridge or lip to hold it in place.
