Reference to these tables leaves me far behind, they are new to me.Regarding to your reference to a 20" Slide rule, I assume you refer to a "stick" slide rule, don't think I ever crossed paths with one. In any case, an 8" diameter circular slide rule, the c/d scale being outermost would give one the equivalent of a 24+" stick or conventional slide rule. That would be sufficient equivalent length, correct me if wrong. Thanks.
