INCHMARTINE TOOL BAZAAR (Scotland). The UK’s premier source for quality old woodworking tools for over 35 years. Here we have a VERY RARE early 20th century Scottish long arm angle protractor with MICRO adjustment by ALEX MABON & SONS of GLASGOW. This is a wonderful quality scientific instrument made specifically for the mining industry. It comes with the original mahogany box with metal makers plate inside. Alex Mabon & Sons were the leading supplier of mining instruments in Scotland in the early 20th century, carrying a range of high quality instruments including theodolites, surveyors compasses and protractors. This specific instrument was used to work out the side angle of large scrag heaps to make sure the angle was not too steep to allow for collapse after various mining disasters associated with scrag heaps. This particular version of the tool with the micro adjustment is particuarly rare. Taken from the massive collection of tools we currently have in stock. There is so much of it. We have the largest web sites of antique and vintage woodworking tools both for users and collectors in the whole of the UK. We also hold one of the largest stocks of spare parts and spare blades in the country. Just google Inchmartine Tool Bazaar to see all. Please note all our UK parcels are sent as follows. We endeavour to send out parcels as quickly as possible but please bear in mind we are in a rural location and sometimes DHL only comes to us twice a week (Tuesdays and Fridays). All our items are packed with the utmost care and attention so they arrive at you in first class condition.
