| Cont'd.{John DeLooze - Company Secretary} At the moment we are not in a position to give you even an estimate of the weights of the complete gun with a power driven mounting, but we see no reason why it should exceed that of the gun with the Non-elevating mounting by more than 100 lbs. We wish to point out that we have no information concerning the allocation of these guns on how many of the first 36 guns will be fitted to your craft. We hope that the above gives you the information you require. Yours faithfully, H.I.H. Verndon, Chief of Design, Gun Installation Section. | ||
