all well and good. I actually did read your post contrary to your assumption. Perhaps it's a glare from camera flash, but it appears to have the same markings that result from the rotation of a nut/bolt on the mounting ear. The object is obviously not in front of me which is why my comment was one of curiosity, which with all due respect does not warrant a snippy attitude as I meant no disrespect to anyone. So to avoid any sort of pissing contest, I'm going to walk away from the thread now.
