| BY/SB.{Mr Bull/Mr Bannister}6/MG.6.4.39 (cont'd) - 2 - We have one cylinder head which we think is reclaimable by facing down the valve seats, and it would be useful if you could use it on the 25/30 H.P. transport car with the water holes in the block modified as shown. We should then know whether to instruct the modification more extensively if we do not run into any other trouble, because this head really ought to go on losing tappet clearance if the modification does no good.
