1. Correct! RS250 (May also be RC30) Easily distinguished as a "racing" calliper by the quick-release pad retaining pins. Also has Allen screws holding the halves together for easier dissassembly/servicing. May be wrong, but I think the calipers will have slightly different piston sizes to the NSR calliper.

2. Correct! MC21.

3. Correct! MC28.
