Thanks for the reply Craig.
Were the 18.5s always like the 22.5s for each year (e.g. same colors, same handle, ash ring, wheels, etc) or are there specific models of the 18.5 that are unique?
Weber dropped the 18.5 OTG at some point, while the 22.5 OTG is still available. I am interested to know if there are other deviations from the 22.5 lineup and when they occurred - this would be good information to archive.
