| X 4289. -6a- C.A.V. Cut-out. (X.1610). One sample model D just received. Will be tested very soon. Price £1.12.6. Weight 14 1/2 ozs. This would appear to be at least as reliable, if not more so, than our present standard Lucas. Lucas cut-out with compound magnetic circuit. (X.4349) A sample model of this instrument was brought by Mr. Breedon yesterday (5.4.21) and handed to us for trial. It should be more reliable than the present standard Lucas, having a compound magnetic circuit arranged in such a manner that the reverse series current produces a definite magnetic pull off. This cut-out will also be tested very soon. Price not yet known. Weight 10 ozs. without cover. | ||
