| Rm.{William Robotham - Chief Engineer} 1124 Hl./EA. 2/JM.{Mr Morley} 1.5.40. Laboratory. Chromium Plating of Cylinder bores. --------------------------------- In order that the position should be clear, Mr.Walker has made a patent search on the above subject, over the past 10 years period. Only one patent, that of Van der Horst, is concerned directly with the method of plating, and the specification is such that it would not affect us. We thought you might be interested to know this.
