Seeking help identifying my dad's Rolex

[TheBeatles]

I was gifted this family heirloom. It was my great grandfather's. He acquired it through sketchy circumstances and the serial and reference numbers were scratched off. It looks like a ref. 6107 face with a ref. 6480 case and lug.
Some help would be appreciated.

I believe it's an 6352 but it also looks like a 6107. I am unsure and could use some help. It has been passed down from my great grandfather. There are no serial or reference numbers so I am having a hard time.
Any help is appreciated.
