Bought used a 18.5 WSM. Code on top vent "CA0386046". Trying to determine mfg. date. 1981 as close as I can get. Anyone out there that can read the WSM code better than me? Thanks in advance. RLV
Things got a bit more complicated in 2013 when Weber started laser-etching a nine-character alphanumeric code onto the lid damper alongside the two-letter alphabetic code. The code consists of two letters + seven numbers—two letters represent the model year using the word “CONSUMABLE” as the key and seven numbers as a serial number.
