| To EH. from R.{Sir Henry Royce} X.3205 R8/W8.12.17. X.3205 - RE CALCOTT. RIM VARNISH & SECURITY BOLTS The rims are size 650 x 65 and the tyres 700 x 80. We do not know the size of the security bolts but the Dunlop people would. We want six security bolts. The rim varnish is for the rims before putting on the tyres. It is something like shellac varnish. R.{Sir Henry Royce} | ||
