Hmm, well I guess it would be nice to have both - maybe one with the Sperry and one with the Bendix - one maybe replacing the 'hack'?
For the moment, the Sperry is more accurate if you consider the production run. The Bendix turret was replaced by a Sperry ball turret starting with the 113th B-17E built, out of a total of 512 B-17Es built by Boeing in 1941 and 1942. So a Sperry ball turret was more common by 286 B17Es (399 Vs 113 of 512.)
