9A Forester's ship-repairer with time to complete crank: a?o?u?t - that's if the previous suggestion of Afoot for 1d is correct (Without horse, a Shakespearian king, also one seen in a Vanburgh play), and my idea of Octavius for 3d (One with me after a short interval, who became emperor), definite letters are o???v?u?
Thanks for those - I always forget that Forester wrote The African Queen, but I'm surprised that Him Indoors didn't spot it, being the resident expert on old films!
