Confirming our conversation of even date. The cost of Mica Washers E.13740 as used in the construction of the Armature, is 42/6d per 100. There are 66 required per Armature, giving a total nett cost of 28/-, to which I think should be added 1/- to take care of Scrap; giving a total of 29/- per machine. D/Rd. AE | ||
