| - 2 - BY6/G.25.3.27. O.K. 6/- The R.R. Luggage Grids will require modifying. 7/ Gear Ratio will be increased. BY.{R.W. Bailey - Chief Engineer} It might be cheaper to change over to well based wheels and tyres, than to carry out the extensive alterations necessary in 3-4-5 and 6. Alterations to wheel carriers will be more extensive to carry 33x5.77 tyres than to carry well base wheels and tyres; coachwork alterations as in 4 are not necessary when changing over to well base wheels. It would appear advisable to recommend fitting well base wheels in preference to 33x5.77 tyres on the existing wheels. AHPudey | ||
