A single round shower handle with no set screw or cap to remove to get to a screw. It is round in chrome with a gold band around it. The shower handle matches the sink handles. Possible close to 20 years old. I have been fixing faucets for myself for over 40 years and I am stumped on how to remove these handles

It's likely that you have some sediment that has accumulated in the cold water valve and has clogged it. The model number you have cited above is only for the trim (rather than for the valves behind it). Assuming that you have a Price Pfister valve, they don't have built in filters, so you're probably going to have to either clean or replace the valve.

After you remove the chrome collar and plastic collar washer (behind the faucet handle), pry the beauty plate off the wall. Turn off the house main water supply. Remove the four screws and washer holding the cartridge and valve stem in place. Save the metal washer under the four screws for use with the new cartridge. Replace the stem/cartridge assembly and secure with the saved metal washer and four screws. Reinstall beauty plate, collar & collar washer, then handle.
