| K.3351 K.3351 BUTS AXLE (C) You will remember that we have had one or two cases where on Dr. Mawhinney's car the wheel was broken by ill-use or by delicate or other design, it should, but we have shown the possibility of considerably increasing the strength by modifying the design, and we hope that none of the old ones will be passed. It will be remembered that the radius on the corner on the outside particularly, wants to be free from scratches so should be finished by having a radius on the corner of the wheel carefully formed, and polished with fine emery cloth.
