As reported in the Minutes of Works Committee Conference of yesterday, we have obtained revised prices of springs from Jonas Woodhead & Sons Ltd. and a comparison of said prices with the prices we have been paying recently would have shown a reduction of probably 7½% on current prices if we had continued to fit rear springs of the thick leaf solid eye pattern, but the adoption of the thin leaf rolled eye pattern, ground on exposed surfaces only, has more than wiped out this reduction and in fact increases the cost of a set of springs of average poundage by £1.18.0d. On the front springs there is actually a reduction of 7½%, but, as already stated, this is submerged in the additional cost of the thin leaf rolled eye rear spring, as compared with the thick leaf solid eye rear spring.
