Glad you liked it; I had to physically (ow!) resist posting at much greater length -- those amber lights up front were controversial in '63 when they appeared, and there were some interesting things said, articles written, and laws passed about them, but this isn't really the thread for it.
Yep. Officially the '65 export cars got clear lenses, but what's on any particular car outside North America depends on what country it was originally delivered to/when it was taken to another country/by whom/etc.
The original bulb in your '66 was a 1034A, with that "looks like school bus paint" easily-scratched-off coating on them. 1034 was the shorter-lived predecessor of 1157. There was nothing such as the transparent "NA" ("Natural Amber") type bulbs in the '60s; those came along in the mid-late '80s.
