Pluck's site has a good bit of info on the San Fran plant.

Considering the first known Sport Coupe built in SF was on Jan 5th, and they built over 3,000 of them in '28, I seriously doubt this was the first one sold in the area.
Really like this part of the ad "NOS "Dog bone" shock connectors."
I've always wanted to do a '28 Sport Coupe but this one wouldn't be one for me.
To each their own.
