Suntour Superbe recessed nut brake calipers! The ‘Suntour’ print on one of the calipers is worn off, shows only minor wear, otherwise in good shape with the original brake pads

Update July 11th: It was pointed out to me by a fellow ebayer that these could be Cyclone brake calipers. There is no actual superbe branding on the caliper themselves, just on the pads.

Message me if you have any questions!
