Looks an assa oval cylinder reproduction. It's definitely a cool lock and will keep you busy for a long time. Unfortunately the first pin is very tall, and may be very difficult for a beginner to move the pick in the lock with such a tall first pin. I suggest you to repin it with just the second and third pins to learn the feel. Once you're confident you can try to add the first one and see if you manage to pick it with three pins...
The pins are assa style double spool drivers. Very difficult ones. Dunno if you've been lucky or not, it's an advanced lock, not the best choice to start with.
Cheers
