Had the blade disk off of my 1979 Victa (gold, not badged, so some presumably a storebrand) to put on a new lower main seal.
I have never seen Victa blades like this, I was thinking it must have hit rocks (I have never mowed with it yet despite having it since feb 2019). Was experimenting with rislone resealer, which worked quite well, but I still didn't want to risk a lawn covered in oil
What gets me is both blades are the same angle exactly - its like they were made that way or someone bent them very precisely
