We beg to acknowledge receipt of your kind letter of the 31st ultimo and regarding the duralumin bowl, we think there should be no difficulty in producing this either as a drawn shell or a hot pressing. We are going carefully into the matter and will send you a sample shortly. It occurs to us that a drawn shell may tend to crush where the thrust screw holds it up to the body and we propose to carry out our first experiment as a cup turned from the solid bar, which would represent a hot pressing. Yours faithfully, BENTON & STONE LTD., Director. | ||
