| EFC. BY/Cgh{W Clough}16/G.17.7.30. X.3495. RE FERRANTI AMMETERS. With reference to the standardisation sheet which has been completed in connection with the above, which we propose to order as an alternative to the Elliott instrument, we would like to know if the Ferranti instruments which have been tested are exactly in accordance with our drawings, or are they their standard instruments. If we have tested out standard instruments then we shall have to obtain a sample of what they would supply to our detail drawing before they proceed with a bulk order. BY/Cgh.{W Clough} | ||
