Looking for pictures of 686-3 recoil shields

[M1Garandy]

I'm trying to help a friend who is looking at what appears to be a nice used 686-3. He says there are some file marks or tool marks on the inside of the recoil shield under the line that the center pin has scratched in it.

Can anyone post some pictures of a -3 recoil shield from the inside with the cylinder open so I can send him this thread for comparison purposes?

Trying to help him decide if this was factory or Bubba.

Thanks.
