Cam identification question

Hi guys n gals, I have just stripped down a 2.0 pinto for rebuild and stick in my escort. apart from +40 thou pistons the motor looks pretty standard.
The cam i pulled out doesn't appear that old and has markings not consistant with standard cams from what i remember.
There are two sets of markings stamped on the cam, the first is on the front face where the timing sprocket sits CE652 and the second is stamped about a third the way along the cam MC24993. The height difference in inlet and exhaust lobes is 6.07mm or around 242.8 thou, maybe a standard replacement? 
Google hasn't produced much and i looked around the sites of most common brands with no luck. I thought someone here may have run accross this cam at some stage.
Thanks

Thanks Avon, Yeh i thought aftermarket replacement because of the lift factor, the numbers CE652 are not cast though, definitely stamped but on the front end. I know most performance shafts are ID stamped on the rear.
 
Cheers
