the lower half of the trem (looks like die-cast aluminium) has broken off.
Ahhh - now I see - the base plate done broke off! Ok, that makes more sense now - it just didn't look right, even for a cheap one!
Here's a great site for Floyd fix tips:

If you just want to say "forget it - I want to just buy a used one on ebay", I'd say go the Jackson route. Here's a list of the ones available and the pros/cons/measurements -

I'd say the JT-500 is a direct drop in (US$40-ish), the JT-590 is the same size, but better quality and more expensive (US$70-ish).
Original Floyd Rose and Schallers run about $150, even used, so don't go there, also, the spacing would be too wide for an imported guitar.
Hope that helps!
