My house is old as well, built around the same time as yours I reckon. A tag on one of the gas pipes has 1958 on it! As far as I can tell the copper water pipes are the original installation and they're handling 86 psi no problem, in fact, the water line into my house is the same diameter copper pipe and it's dealt with city water pressure since the place was built. Not sure it was always at static 110 psi, but it has been since I moved in 2004. I did have a pinhole leak between the city's shutoff valve on the street and my house though. Had to get the yard dug up to repair, but it's patched and holding up fine. I still have more confidence in good old copper pipes than the new plastic stuff.
If you have a PRV it shouldn't be too far downstream from your water meter. If its the same Watts 25AUB, it wont' be difficult to adjust at all, in fact the spec sheet I pulled off the net says you should clean out the sediment screen from time to time. A wrench & screwdriver (pressure guage too I guess) is all you need to adjust the pressure. Loosen the locknut with the wrench, use screwdriver to turn the adjustment screw clockwise for more pressure, counterclockwise for reduced pressure. Once you have the desired pressure, tighten the locknut. Edit, might be two wrenches, not screwdriver.
