Simplified Speedo Drive. N.Sch.4922. In reply to E {Mr Elliott - Chief Engineer} /Hdy. {William Hardy} 1/HP.13.10.36, regarding the above, we wish to say that although N.Sch.4922 does not give the same economy as WKS.194 we agree that the saving offered is worth while. The design objections against using our scheme in full we now appreciate. We note also the modifications outlined in paragraph 1 & 2 of E {Mr Elliott - Chief Engineer} /Hdy {William Hardy} 's memo' which should however, give us further saving.
