Well obviously something has been done to it unless it was totally shabbily built. Look at the gap where the extension fits into the cut in the frame. Of course I suppose someone could have taken a big coarse file to it & flattened the rear, But WHY. Filing removes metal & would make the fit looser, peening expands metal to give it a closer fit. Also if you look closely at the picture you can see the expanded metal on the top of the extension, normal for peening, abnormal for filing or grinding. I did put in over 35 years as a machinist, I can generally see the difference in peening & metal removal even from a picture, if I could look at it up close it would of course remove all doubt.
What do you see that says it "WAS NOT PEENED???"
Just present facts, don't try to snowball me, I've been going down the tracks for a long time, seen a lot of water run over the dam & seen a lot of Uncouth Fixings.
