Bailey - Chief Engineer} c. to DA.{Bernard Day - Chassis Design} C2/C6.6.28 We have no trace of 50 bodies being put through with semi-isolation. All we know about this is that a standardisation sheet was sent round for the 20 h.p., and only this week a standardisation sheet for semi-isolation was sent round for the 40/50 h.p. which has been signed in London.
