Help with Rolex Milgauss 6541

[Jaystrab02]

Hello Rolex community!

I’m new to this forum. I was trying to get some help with my current situation. I acquired an estate lot from a watchmaker and found an old Milgauss in a project tin. It is the version with a honeycomb dial and no lume so I have done some research to determine if is most likely a later version of the 6541. It has a little rust around the triangular markers but in great condition. It does not seem to be a replica from what I’ve seen. I’ve looked at the Minh dial but the “R” in Oyster-Perpetual is different. It has the antimagnetic cage and a 1065 movement which is puzzling to me but I have seen some with the 1066 movement but also some posts that a 1065 M will fit so I don’t know if that is the original movement or if it was meant to be used with the watch as a build. I was hoping to get the dial and movement recased and maybe eventually pick up a riveted bracelet but that will be later on down the line. I was hoping someone could help provide any potential options. I know the case should be a 38mm but I was curious if maybe anyone knew any genuine Rolex cases that would also fit. Maybe a case reference from a sub or any other piece. I want to use a genuine case if possible but I have also seen that there is a Minh case that is a very close replica. I was hoping that anyone could provide any advice or information on the 1065 movement and if it will work for this watch if it had the antimagnetic cage. Thank you very much I really appreciate any help and insight. Also if anyone knows if I can use any bezels aside from the available replica ones?
