How would they do that? Unless you do a general retuning (that usually involves shuffling the pipes and creating substitutes for the low end), most organ pipe types can very much only be tuned upwards with some reliability. So after a general tuning, they tend to be somewhat below concert pitch and over the years go higher with each tuning. Unless we are talking electronic organs, an organ that is 440Hz straight should be either brand new or electronic or coincidence.All these organs were tuned to 440Hz.
