Nikon F with FTN Photomic Meter, Nikkor 135mm F3.5 lens, non-AI, single coated version. The FTn Meter Head was introduced in 1969, and continued until production of the "F" ended. You can tell if a show pays accurate attention to detail if you see a "T" head if set before 1968. A "Quantum Leap" episode set ~1968 went to that detail. Sydney Poitier used an original Nikon F with "Bullseye" Photomic head in "The Bedford Incident". A "Tn" head added a tiny white button for battery check, and went to 60/40 center weighted metering. How come no one gets "Close-Ups" of the cameras!
You can just make out the Meter Release Lever that holds it to the body, prevents Photomic Fly-Off syndrome present in the Photomic, "T", and "Tn". The 135 F3.5 has a fairly unique (for Nikkor lenses) deeper-Blue Coating on the front element.
I'll try to remember posting a shot of my setup like this.
