Can anyone identify this gyro?
Neither the part number nor the logos are familiar to me, and I'm assuming that you've already done the usual Google searches, tried to narrow it down by package size/pin count/axis count on distributor sites, and looked for the repair manual and replacement parts lists.  If no one here recognizes it, the next (and possibly last) step is to try to contact the remnants of the manufacturer.  

What kind of info are you looking for?  If it's analog (Plugged into ADC pins or buffers), you should be able to reconstruct what you need just by soldering on some test leads, powering it up, and waving it around. If it's over a digital interface, I wish you all the best of luck in deciphering the init sequence, command set, and data format.  

That said, unless you're trying to upgrade your hover toy, I think your needs will be better served by purchasing a new one with a known manufacturer, datasheet, and distributors.  It's perfectly reasonable to pull off sturdy, easily identifiable parts (switches/buttons, potentiometers, LEDs, and connectors are generally the first things I reach for) but I would generally just leave unknown ICs, ESD/age sensitive, or highly variable parts where they sit.
