Mice! Posted September 18, 2023 Report Share Posted September 18, 2023 I've always called them Telle gauges, telescopic,, you set them in a hole on an angle, nip them up and pull towards you so they adjust to size, can take a few goes to get a feel and repeat size. Funny when lads can't use them because we have bowers these days. Quote Link to comment Share on other sites More sharing options...
