need help identifying parts

[dude!]

hi
I recently bought a modded crf50 with a box of spares, there are two cams, one of them the guy reckons is takegawa (left?) which has a higher lift than the other but there are no marking or inscriptions, the other has HCDC NO:26 (right?) on one of the lobes. can someone identify these cams or point me in the

cam on the left has better machining marks rather then the casting on the right

yeah and larger lift but im guessing not takegawa. does a standard cam look like the one on the right?
