The Works will be immediately instructed regarding the addition to the top water pipe which is necessary to accomodate the bulb for the thermometer, and 250 sets will be ordered in this way. It is desired to fit this bulb for later chassis (after 250) directly in the radiator, in order that the dismantlement of cylinders can be effected without disturbing the thermometer bulb end tube. The manufacturing of 250 sets in this case, instead of the full 500, is thought to be reasonable in view of the class of work to be undertaken, but in the event of disagreement regarding this number I would like you to consider the matter as being open for discussion. It is also agreed that if necessary the first few chassis will be delivered without thermometers at all, but these can always be fitted merely by changing the top water pipe, providing space is allowed on the instrument board according to the standard design for this part. The design for the water pipe fittings is similar to that at present on 49-GR.{George Ratcliffe} | ||
