Dear Sirs, With reference to the gauge face which you are preparing for the 40/50 HP. The first gauge which we require will be used exclusively with 50/50 spirit. We should therefore be obliged if you could calibrate the mask accordingly. We are returning to you under separate cover 4 carburetters which we have been recently trying as we have been unable to get satisfactory results from any of these instruments. Yours faithfully, | ||
