Hello all! I just joined today. I've been on the hunt for a used 18" WSM. This past weekend, one popped up on Facebook Marketplace. I knew it was older because it had a wood handle on the lid, but I didn't know how old. I asked the seller to tell me what letter was stamped on the vents. It turns out that it was made in 1993. The best part..... it had never been cooked on! The seller knew they had had it at least 20 years. They put it together long ago, but never cooked on it. I'm now the proud owner of a used, but new, 27 year old WSM!
