Looks like it's just sanding/grinding marks from deburring the casting flash from the part. Different workers in the casting foundries will give different results in that regard. Some will treat it with care and finesse, others will be ham-fisted morons that will grind half the casting away to remove a 1/16" burr. I'd say it's perfectly normal.
