Lynn Bremer of the Mission Archive-Library provided the answer. Her research indicates that these precious religious artifacts did not disappear. Ms. Bremer informed Pentacle Press that "What remained of them after the 1925 earthquake, are in the Mission Museum."
"Faith had disappeared before the first photo of the Mission was taken in 1860's. Hope fell apparently during the earthquake, and Charity and St. Barbara were severely damaged and had to be removed. New statues were made (not copies) to take their places."
