A Beaulieu R16, given a clean, original manufacturer's markings removed and a coat of hammerite paint applied.
The R16 appeared in a number of different forms over the years, starting out initially as a spring wound camera. Although not crystal-synced, the motor does run in a closed-loop control system and is pretty stable. I've been able to tweak the shutter speed on mine using the roll-bars of a CRT TV to get it pretty darn close to 25fps. An optional pilo-tone generator was once available as an accessory that would allow double-system sound (with a compatible tape recorder), although the cameras themselves are far from silent!
There are various versions of the instruction maual available to download from the internet for free, here's one example, and the brochure for the R-16 Sync. There are other original adverts and brochures available as well if you search for a bit on google.
