Found a snowboard by the dumpster

With a bag and boots just my size :) I only go boarding one week a year so can’t test it yet. I’ve never owned a snowboard before and the ones I rented have been a lot more flexible and narrow. Can anyone explain the difference?:) The back also has some weird pattern and not sure if it’s normal. (Or maybe because it needs waxing?) I also can’t find the specific board online so an id would be awesome Thank you :)
