In the specification provided by W. the c.c. is given as 7,338, whereas when I spoke to you or your Department on the telephone once they gave it to me as 7,340. Furthermore, whereas the specification quotes 50.7 h.p. R.A.C.rating, I was given over the telephone 50.6. On the basis of 3 1/4 x 4 1/2 bore and stroke I have checked this up and find it to be 50.7. Will you please confirm that you are in agreement with this, and whether the c.c. is 7,338 or 7,340. Also, in the specification is says " The connecting rods are of the marine"type". Would you please tell us what this really is, in case customers ask the question. Please reply by return, if possible by bag, as the catalogue goes to press immediately. Cx.{Major Len W.
