I have two mop dots just behind the string holes on my Tanglewood, which I assume are covering two bolts or screws, the strings however do come from the rear of the bridge like a classical which would make sense.
The bridge in your pics are are pins, which wouldn't really need any extra anchoring in my opinion, that's not to say they aren't screws or bolts. On the surface of it, it seems like a striaght bridge gluing job. But on the other hand when you start to take things off, that crack may go a little further as it depending on the rest of the glue joints inside the guitar. But if it's unplayable and no resposnibilty on you if it goes pear shaped then give it a go.
