The quality of the reblue looks good, although shinier than factory sheen would have been in that era, with the exception of some speckling that's occured since. Hadn't considered a peep, I'll try a 57.
The box of treasures is what makes projects like that possible. I've had that forearm for years. The old band fit the barrel contour perfectly, and everything is as tight as a vault. It's critical on cutting the notch in the barrel that you cut and fit, cut and fit until it's snug but threads right and locks up. I'm happy with that.
