Currently working, but can’t test for time as missing the minutes hand, balance staff is good, maybe ticking a tad slow. It may need a service to keep time, has sat idle for a while and needs a minute hand. 1952 Hamilton, Grade 992B, Model 5, 21J, 16S, lever set, stem wind, 6 adjusts, railway grade, Montgomery dial with date serial number C363028. The gold plate case is 51.2mm in diameter. Nice dial, just needs a light clean, skeleton case back will need an adjustment, doesn’t quite screw down flush with the case, some plate loss to case on the edge.
