can anyone ID these brakes?

[Sharkey]

i bought a set of brakes on ebay, i assumed they were mecatechs being they are twin piston calipers, and the only company i can find that makes twin piston is mecatech. now that i have them they don't look like mecatechs, at least not the current model.

as you can see, the brake arent held in with pins like the mecatechs, they screw on. there are no markings on anything. im needing a couple of seals for them (bladders in the lids of the master cylinders) and some rotors. the calipers have steel pads and rotors, so i either need some composite rotors or different pads.

any ideas on what they are and what parts fit would be appreciated
