Referring to your memo D/BP/WK.1/DP.16.11.38 enumerating the special features fitted to B.144.LS. kindly note items Nos.3.4.5. and 7 are standard on 'M' series chassis. Regarding the other items, we propose to deal with these as follows:- (1) High compression cyl. head and special thin gasket. - This will be fitted to B.156.MR. (6) Brake drums and servo ex B.24.GA. We propose to remove the front brake drums and hubs from B.144.LS and fit them to B.156.MR. The equivalent parts will be removed from B.156.MR and fitted to B.144.LS. In regard to the question of finish of the Brake Drums and wheels, these can be primed for silver cellulosing if necessary. Mellotone horns only would be fitted to B.156.MR.
