I just found the 'Assembled in Vietnam' written in the mount itself, so I guess that answers that question. I hadn't seen any of these until now.
It looks like your first lens is an original Made in Japan lens, and your second lens is, like most Pentax lenses now a days, Assembled in Vietnam.
There have been many questions about the 645 lenses as to whether they were still in production, or whether Pentax/Ricoh were just selling old stock.
Your second lens seems to suggest that the 645 FA lenses are still in production, but that they are now Assembled in Vietnam rather than made in Japan.
This is good as Ricoh therefore have invested in an assembly line for the 645 FA lenses in Vietnam. Another positive sign of continued Ricoh investment in the Pentax brand.
