| R.R. 235 A (100 T) (S.F. 575. 16-4-19) G.{Mr Griffiths - Chief Accountant / Mr Gnapp} 2354. COPY. SPECIFICATION ETC. OF "RAPSON" JACKS. Price of four Jacks complete with axle fittings, - Retail £15 - fitted £16. Manufacturers discount 25% if standardised otherwise 20% Special Note. These Jacks are extremely costly to manufacture, the castings being made of special "Millenium" steel not malleable as all others are. They cost us £9. Weight. The Jacks being sent weigh as follows, but our standardised models are reduced in the axle fittings - Front Jack:- weight 5 lbs., swivel device 1½ lbs. axle fitting 5 lbs. (reduced to 2½ lbs.) Rear Jack:- weight 7 lbs., swivel device 1½ lbs. axle fitting 3 lbs. SPECIFICATION CONFIRMED. Obviously if Messrs. Rolls-Royce Ltd., decide to standardise, it would be very simple to cast as a part of both front and rear axles the swivel fitting, thereby entirely eliminating weight and cost of axle fittings, which would reduce weights to:- Front axle complete - jack and swivel lock - 6½ lbs. Rear " " " " " - 8½ lbs. Were this carried out, instead of supplying you with the jacks at £11-5-0 - Retail £15, we could reduce to £10 - Retail £15., shewing you clear profit of £5 per set. Yours faithfully, F.{Mr Friese} Lionel Rapson. | ||
