The lever has been ground down a bit so that it can engage the latch. Not sure why someone would do that when it is easy enoughto just turn the latch so that the lever can be secured. Oh well you never know witht some folks. I have included a photo of one of mine for comparison.
I did also notice that the stock has been dramatically sanded down and is undersized where it meets the receiver. In your second photo you can see how different it is from one side to the other.
