Looks like you've got a pretty basic single sided wafer lock, there. You often find these on electrical lock boxes, tool chests, mail boxes, and file cabinets. In my (limited) experience, cheap wafers like that are fairly simple to pick using the pics in even the most basic of sets. Some are so sloppy that you can basically just apply light tension and wiggle a pick around and it will pop.
As wafer locks have less depth options than conventional pin tumblers and frequently have a lower number of pins, they are highly susceptible to raking. If you want to pick this lock and you're interested in getting started with picking in general, buy a tension wrench, S rake, half diamond pick, and hook pick. You should then be good to go for this lock and you'll have a good base kit to build upon. Shouldn't cost more than $20.
Refer to this thread for more info on wafer locks and how they can be compromised.
