D.{John DeLooze - Company Secretary} Dept. X8810 By 9/G3.2.30. X.4554 X.8810 X.8820 WHEELS AND TYRES - SECOND HALF OF L.2. SERIES. Will you please note that the Experimental Dept. now inform me that they have satisfied themselves that the 20" rim is perfectly safe and satisfactory for production use. Standardisation sheet is signed up, and will shortly be issued. The tyre for use with the 20" rim is the 'Fort' type size 32" x 6.75". The "Fort" type will now be our standard, not the normal as with 21" rims. By.{R.W. Bailey - Chief Engineer} | ||
