Chaser as cutter Saigon

Just posted is a scan of a newspaper file shot of a chaser post-war, about to be fitted out as the Coast Guard cutter Saigon. The date stamped on the back is May 9, 1923 -- which makes sense. See the photo page, here, for the newspaper article attached to the back.

Unfortunately, it doesn't identify which chaser it is, and so far, I can't find a reference. Does anyone have Saigon on a reference list?
