| (sheet 2) recommended source of supply direct. We take it that there are two types of spring discussed in the report, namely springs hardened and tempered after winding, as in the normal way, and springs wound from tempered wire. The relationship of these two types however is not very clearly brought out, and we are endeavouring to obtain some further information from America on this point.
