Bridge assembly is typical of the Japanese approaches to vibrato bridges of that era.  Notice that the 2 rear up-down bridge adjustment screws are also missing;  It's a common screw hardware part.  All visible parts on this guitar are in very good shape and should clean up well.  The volume & tone knobs are common to Japanese guitars of the period.  I might even have a few sets in my parts bin.  I do not do such detailing on most guitars when I purchase them and before offering them for sale;  Otherwise many of them would sit awaiting their place in line for my work bench for which I would have to tack on work costs.  Eventually every guitar will make it to my bench for detailing work;  But in the meantime many folks appreciate bargains needing minor parts (some Folks ....like me ....even if major parts are needed). 
Univox 12 String

Bridge Parts Details:
Details of adjustable bridge saddle pieces.  The hairs in the picture is dust stuck to the light lubricant applied to protect the bridge while the guitar is stored (it was done professionally and doesn't impregnate the guitar finish and screw holes).  The bridge pieces are proprietory to the guitar and probably other Univoxs;  But would not be difficult to fabricate if a part could not be found.  The base boss piece is stamp cut from steel stock in a + pattern, then stamped into a shape where each + wing folds upward to form the boss box shape which is drilled latterally and threaded longitudinally.  The saddle piece is knurled stock similar to period Gretches, with a center axle hole and cut to width and secured into place by a pin that is pressed on the ends like a rivet.  A spring loaded screw is threaded through the threaded holes on the longitudinal axis.  The knurled saddles allow for string spacing adjustment.
Close up of the tuner gear that the last owner used for a bridge piece;  Amazingly, it works well !  Also shown is the detail of the threaded receiver that the vibrato arm screws into like most Fender guitars.  Although some current metric threaded "Strat" type arms might fit, ....I would not hesitate in the to rather easily fabricate a vibrato arm from stainless steel rod.
Bridge assembly is typical of the Japanese bridges of that era.  Notice that the 2 rear up-down bridge adjustment screws are also missing; It's a common hardware store screw.  I have the screws and a bridge saddle and can provide same if I haven't already repaired it by the time a customer desires this guitar.

For anyone searching for these parts; I have seen very similar bridges on some Univox, Arai / Aria, Dominoe, Raven, Tempo and other Japanese jobber guitars;  Suggesting that the bridge's origination might be Arai / early-Aria.
