@Harbormaster so we've seen "B" code vents on WSMs?
because we ran into the same circumstances where some units had a prior year's vent code assuming they used up the old vent stock before switching to the new stock. the 2015 performer i traded to brian has an AH coded vent which would make it a 2014, but it had the new table, lid bale etc and we believe it was used in a photo shoot. i believe there have been other instances that came up when we were talking about vent codes.
so it may be that the units were produced the year weber states they were, but received left over vents that didn't get used up the prior year.
i have no idea, i'm not saying anything definite, just purely speculating.
604's, i mean #001's new first in north america MT has a AH vent code, which would make it a 2014 model, but it's a 2015 offering?
it's also been speculated that the vent codes run with the calendar year and not model year so who knows for sure.
way to derail your own thread greg.
