What kind of calipers are these?

I bought a set of calipers cheap a while back, and I've been thinking about fitting them for some time now.

The problem is I have no idea what pads or discs they are for!
I can't find a part nr on them, but the mounting holes fit with a a set of brackets I had lying arond for a Big reds set, and it seems to go over a 323mm disc. The Big red pads doesn't fit too well though, they are EBC pads and they're 1-2mm too long.

I haven't measured the pistons, but I did take some pictures. It doesnt look as bulky as I remembered the small reds to be.

measure piston diamiter, and distance between bolt holes

Looks like "big reds"

looks like someone painted them with a catapult??? make sure you clean all paint from the bolt holes as it will crack up and work loose

The distance between the holes are the same as big reds

The paint job is horrible, but the seals look allright.

I suspect the pads don't fit because of the plate lift.

If you remove the metal plates and remove the corrosion from underneath, you should be able to refit the plates and try the pads again. You may need to bend the plates flat as they are distorted.
