Unknown brake calipers

[Gas409]

Can anyone recognise the maker of the four pot front brake calipers fitted to my S1 E type? They are not Coopercraft or Zeus. They are British made but with no maker's mark. I think that they were fitted between 2010 and 2015.
Thanks, Rob Herrick

They are probably BCC calipers:

The layout of Allen bolts with bleed screw in between are indicative of Coopercraft. Although normally silver, yours may have been powder coated black and hence no markings. Here’s a couple of images showing Coopercraft layout (vented version).

You may be able to tell by measuring the piston diameters and comparing them to known brands.
