Origin: To avoid unnecessary fitting for large number of cars. Experimental Test Report. The proposal is that the exhaust cut-out should only be fitted when requested. Not having the cut-out - avoids having the slot in floor-boards - avoids a source of rattles, and possible source of exhaust fumes getting into the body. Road Test Report. We suggest cut-outs are undesirable on covered cars. The advantage in power is only apparent above 50 m.p.h. Adopted by Springfield. Drawing No. Part List A Scrap and replace at all costs, including Chassis already delivered to customers. B Scrap and replace on Chassis in works. C Scrap present stock and replace on all Chassis not yet handed to test. D Use existing stock Alteration effective on future Chassis. Weight of Old Part.
