I picked up a 64 .30-30 with Lyman 56 aperture sight for around $750 at Whittaker Guns in Kentucky 3-4 years ago. It was in excellent condtion--but it wasn't original: Long ago, somebody had fitted a Pachmayr ventilated pad long ago, which I replaced with a black 1/2" Decelerator. They can go for pretty fancy prices when all original.
That seems like a sweet deal. Price lowered due to the pad your smart wife knows belongs on just about any rifle, a proper rear sight, and a vintage steel one to boot. What year is it?
