| 1123. To By/Cgh.{W Clough} from Hs{Lord Ernest Hives - Chair}/Rn.{Mr Robinson} Hs{Lord Ernest Hives - Chair}/Ru.6/KT.10.8.3 2. Should like a print of these dimensions. I think we can, with advantage, try the Peregrine pipe C. in 18 S.W.G. (.092) as well as 12 S.W.G. When we get a free-r system we shall find that the fish-tail and swanneck too small. On our latest 25 HP. system we have had to use a P.II swanneck. Recommend we use 1.750" O.D. pipe for the swanneck with correspondingly greater fishtail area.
