High Speed Battery Ignition. Sg{Arthur F. Sidgreaves - MD}18/H2.1.34
SpectreCodename for Phantom III and Bentley.

I have just been reading Hs{Lord Ernest Hives - Chair}/Wst.3/MA.29.12.33 and am very glad to see the big improvement effected by the new cam.

I notice the report says that the former cam to LEC.3323 gave very poor high speed characteristics and it was found that it had been wrongly designed, and I am wondering whether there is anything sufficiently important about this to necessitate the alteration of present production.

I should rather doubt it as I have not heard of any actual ignition troubles aixx other than the seizing up of the make and break, which of course was quite a different point.
