I am going to take some more pics in higher resolution. I am no mauser expert, but given who apparently used this rifle, my guess would be it was semi-custom and I have never seen a sight like the one on the front - as i said it is a 4-beaded swivel machined into the front sight base and swivels offering different color beads. It had an old zeiss scope with claw rings, which were lost during a move (I know, bummer). I am going to give G&H a call. I think they are the ones to take this to. Not looking to spend an arm and a leg though and would love to locate a period appropriate zeiss scope with claw mounts. I tried to get this done about 3 years ago, but some family issues prohibited this.... so here I am again. Thanks for everyone's input. Much appreciated.
