| Date | 1st October 1911 | |
| R.R. 140 / 120 - R.F. 579 S&C(S) G.{Mr Griffiths - Chief Accountant / Mr Gnapp} 1823. The Lighting Dynamo X295 Half load as controlled by switch also works satisfactoril, the little resistance bobbin which is fixed in the switch when working under those conditions is inclined to get rather hot, at the same time does not seem to get overheated after long run. Tested by Harris October 1911. | ||
