Typed Subject: Re Bentley - Fabroil Timing Gears. Typed Body: Further to memo' BY5/G.13.12.35., re above, we have looked into the question of including this type of gear on the "big bore" engine, and find that with incorporating the 20/25 HP. type of cam balancer on this chassis it is not possible to fit same, therefore, some revised designs would be required before they could be fitted.
