| 1260 G/Rb.{R. Bowen} from Rm{William Robotham - Chief Engineer}/Swdl.{Len H. Swindell} Rm{William Robotham - Chief Engineer}/Swdl{Len H. Swindell}1/R.20.5.38. WRAITH & BENTLEY III. Could you please give us a comparative factory cost estimate of the following pieces:- (1) Rocker Cover Thumb units (3 per unit) E.60743 as standard in BZ/S against similar nuts in S/M nickel deposited with the knurling deleted. (2) Rocker arms EW.1409 with bronze bushes fitted EW.1410 against similar rocker arms whitemetal lined and reamed to give approx. metal thickness of .025 - .030. The peg and boss used in conjunction with the bronze bushes to locate same will, of course, be unnecessary when in the case of the white metal lined rocker arms.
