- ANNUAL SERVICE by Smith of Derby (Jonathan Lee and Matthew Smith). I asked them not to interfere with the escapement or the pendulum. They investigated weights scraping against the stonework during winding, found that the First Strike (Trinity Strike) was scraping. They will make a minor adjustment. Also invesitgated the uneven winding of the Going line on the Going drum. We tried refitting the line at the ratchet end but found that the line then interfered with the quarters advancing bar. General service involving oiling and a check over. As a result, pendulum amplitude has dropped. I wonder if it will recover?
