X.3855 X.8180 X.8190 In reply to your memo. Hs{Lord Ernest Hives - Chair}7/LG5.3.26., concerning BY3/H3.3.26., I am sorry but I do not recollect anything in connection with a point being raised by BY.{R.W. Bailey - Chief Engineer} concerning these washers. As a matter of fact we are recommending the use of soft alum. washers in connection with the revised spherical unions, and we should consider they were equally suitable for the drain pipe union in question.
