Handwritten notes: TMC 2-10-0 less 16? 2-4-4 less? Ø - (N.B. 4 nuts only to give comparison.) EXPLANATORY NOTE:- (a) The extra cost over Bentley equipment is largely due to the special design of Wraith wheel nut, which accounts for 42/- of the difference if unplated parts are compared on a 4-nut basis. (b) Additional work is also required on the hubs, and furthermore, our quotation is based on an initial absorption of 200 sets only. We should welcome the opportunity of reconsidering the position upon completion of that quantity. | ||
