This year I’ve purchased two Model 642 Smiths, a 4” Model 686+, and a Model 627 Pro Series. They’re all as good as can be expected from machinery, and I check EVERYTHING. Cylinder timing is perfect, no end shake, canted barrels, and lock up is tight. I did buy a Model 36 Classic in 2019, and that had a couple of shavings floating around. A quick blast of compressed air solved that, and it works dandy.
