| Wor{Arthur Wormald - General Works Manager}/Ker13/L7515. 20/100 Re Experimental Chassis. D.{John DeLooze - Company Secretary} Sn.{Mr Sanderson} Order Office. Sy. E.{Mr Elliott - Chief Engineer} Ds. Hy.{Tom Haldenby - Plant Engineer} EH. 7.5.15. Mr Chandler has suggested and Mr Wormald has agreed that owing to the fact that when an experimental car is sold it is usually a mixture of a number of different series and special parts, it would greatly facilitate dealing with same and also prevent mistakes in supplying spare parts if all experimental chassis numbers are terminated with the letter X in the same way that other chassis have had the termination E.{Mr Elliott - Chief Engineer} Chassis 2300 has now been re-numbered to 2300X. Will you kindly see that in future this is carried out and existing experimental chassis are altered accordingly. Mer. | ||
