| 206 also 200a To By/ALD.{F. Allwood - Experimental Design} Rm{William Robotham - Chief Engineer}/JBD.{John B. Dixon - Fuel Systems}14/JH.3.6.38. LOCKHEED FRONT BRAKES FOR 3.B.IV. to drg. SCD.148. Will you please make the following alterations (1) The adjusting cam is now shown in the reverse position and should be turned over. This is also shown wrong on Lockheeds drawing. (2) The adjustment assembly is shown fitted in a clearance hole in the carrier plate this should be located in a slotted hole as shown in dotted line on the Lockheed drawing. We require another set of Lockheed front brakes similar to those now fitted to B.56.BN{W.O. Bentley / Mr Barrington} but with the alterations called for above. These are to be fitted to 3.B.IV to enable us to fit up an arrangement using pedal operated hydraulic front brakes and servo operated Girling on the rear. Will you please instruct the necessary parts. Rm{William Robotham - Chief Engineer}/JBD.{John B. Dixon - Fuel Systems} | ||
