1968/69 DJ 1601 in question

[MUCCI416]

I'm posting comparison photos of a 1601 & 1603. Looking for opinions on the 1601, engravings, case and dial. I already have my own opinions about the engravings being sloppy and that I have never seen a 6 like that on a Rolex. The case not having an ellipse to accept the movement and the dial being refinished as it doesn't have a step (Pie Pan) as well as the font being wrong.
Opinions?

Engravings:



Case: Top is 1601



Dial: Top is 1601






Thanks for all your time, I apologize for the size of the photos.
