Beautiful box of vintage slip gauges and gauge holders Matrix by Coventry gauge and Tool co. E81 81 slips and 2 protective slips. All present although some show signs of discolouration (see photos) and a few have a number etched on. Second layer of holders, again all present and in wonderful condition. All in a wooden presentation box. This is a rare and special set of combined slip gauges and holders. The set is heavy at 9.1kgs, so local collection is welcome (but also happy to post.)
