It doesn't look like damage honestly but then again that is why I came to you guys the actual experts. Would be a hard place to get damage like that without leaving proof other marks. When I look at it under the microscope it looks like there are 3 lines converging coming from the elbow, and the bottom left hand corner of the 2 Ls. I have no idea what it is just weird it happens in the same spot all the DDO are in. Not saying that is what it is but something is going on there.
