Barton has an ancient "door-frame" frame clock believed to date from 1735. This was inspected by the diocesan clock adviser, on the 27th January 2022. 
The clock is much earlier dating from 1670-1680; the 1735 date being graffiti. It is a rare 3-drum clock, the drums being (from top to bottom) the hour, the quarters and a chime. The clock was formerly in the tower, the bells being connected to the clock by wires and pulleys. The drive was by rope wound round the drum and passing over pulleys from which weights hung. Three weights exist one of which can be seen under the clock above. Also existing are two wooden disc pulleys and a bell clapper. These are also rare survivors. The clock is largely intact which is also rare. The manufacturer is unknown due to the loss of name when the top bar being renewed in the 18th century. 
The date places the origins to the Sacheverall family who had possession of the manor —probably Henry whose tomb lies in the chancel. 
Examination of published clock history has indicated that no-one has given it any serious examination in 200 years and commentators just record its presence quoting the incorrect date (as has been done in Southwell history project). Three drum clocks are rare.
