I picked up this old Peterson shape number 10 at a flea market for about $12. This one needed cleaning inside and out as well as reaming. The finish was quite good. I just used a soft bristle tooth brush to get into the crevices. The shank had a crack in it so I banded it with a silver band. The bowl was caked and very narrow. I used a battery terminal brush and an old adjustable reamer to get inside of it. The stem on it was obviously not the original but a smaller diameter replacement stem that did not fit well. The shank had been sanded smooth but was not tapered to meet the misfit stem but it was perfect for setting the band. Before doing that I used some super glue to squeeze the crack in the shank together. I held it until it was dry. I then heated the band with my heat gun and pressure fit it on the shank. I flattened the bottom edge of the band to match the flat bottom where the stamping is. I fit and shaped a new stem. Once it was fit I bent it to a comfortable fit for the mouth. Then I sanded and polished it with my usual regimen of micromesh pads from 1500-6000 grit.
