Which kind of Camshafts are the ones?

Hello everyone.

I have a question. I have two sets of camshafts, and the question arose because they have different numbers even though they appear to be the same. I add photos. Do they have any difference?

They both have the numbers 257 and 312, but where they change is that one pair has L-15 and L-17 and the other pair has L-29 and L-30.

I really appreciate the help!
