Those pictures are fantastic. They are unprecedented, in that they show some the most revealing build practices to date for SF: the base, the vent, and the stand/mouth construction.
SF is fast becoming one of the most sought after ovens. NP joints are sprouting up like weeds all over the country, and it seems every one of them has a SF oven. Forno Bravo just came out with 3 new lines to compete with them (Modena2G, Professionale, Premio2G) as I think they see the writing on the wall as well.
