I'm not sure of the manufacturer however the 268 would be in reference to the duration and HR 10 would be in reference to the lobe separation angle. HR would typically be "hydraulic roller". As sort of a swag I'd suspect it's a single pattern cam on a 110 LSA with somewhere around 224 degrees duration at .050". If you have a cam grinder anywhere near you they cam put it on the cam doctor and run it for you to see what it really is.
