These tools were obtained as part of a jewellers/watchmakers estate sale and, judging by the other items, probably date to the second half of the 20th century. They could be used for both clock and watch pivot repair and replacement. Offset runner, 7.5 mm diameter marked Boley & Leinen. Cone plates for holding arbours whilst the ends are drilled. Hole sizes from fractions of a mm to approx. Drilling runner with drawbar and 2 collets – shown with a drill bit in some pictures (not included). Jacot drum numbered 2.8 – 11 for supporting pivots whilst polishing (marked Leinen). Centring runner for aligning drum/cone plates. This is probably the most useful accessory for a watchmakers lathe – because it enables a consistent and professional approach to re-pivoting – a very common requirement in the process of clock/watch repair or restoration. Please ask if you need any further information. Please ask for a quote if you are interested. Alternatively collection is not a problem if this is convenient.
