what rear calipers are these?

[green_rs13]

I picked these up ages ago in a job lot and don't know what they were off.
my current calipers and discs are buggered so I may aswell bung these on but don't know what size disc to buy.

calipers are not really my area of speciality so what are they?

They are a perfect fit and very easy to install.
