X7941E LEFT-HAND CHASSIS FOR AMERICA. With reference to the points raised in WHr{Mr Wheeler}/Rol6/WP21.5.30., the following is the position as known to the Expl. dept. :- (a) Body Subframe. - Not to be supplied. 25-EX, which is going to America is fitted with a subframe. We still hold the view however, that if consideration is given in the construction of the body the subframe is not essential. (b) Exhaust Cut-out - Not to be supplied.
