Going over some of the differences between these plates lately. The spoke ends are shaped differently and the Hubs are different heights as l show in the video. Not shown were the Deep Dish York plates with "45" on the face. The Hub and spoke ends are like the DD 20 Kg plate. There are only about 7 pairs of the DD 20 Kg plates known. The DD 3rd Gen 45s were made for a quarter of a century. It can be fun digging into all the details! God Bless!
"There is therefore now no condemnation to them which are in Christ Jesus, who walk not after the flesh, but after the Spirit. For the law of the Spirit of life in Christ Jesus hath made me free from the law of sin and death." - Romans 8:1-2
