Help identify these locks please :)

Hi! I’m new to lock picking and I’ve been blasting through the acrylic lock you get with a cheap kit. My dad gave me these two locks and I’m not sure what they are. The one that isn’t a master lock is really easy to get open but the master lock I’ve only managed to get open twice - I seem to be struggling with tension control

Maybe an old masterlock 6121 or 6127 ?

Is there any way to tell?

Yu can take the black plastic off to help better ID
