Was there ever any records relating to cross checking this info so as to know if our ladies are still the original as built by Remington caliber?

no such data exists to my knowledge

From what I've read.
Only tell tale signs a gun isn't original caliber would be a first year production autoloading rifle " model 8" being anything other than 35 remington. Another non-factory example would be any model 81 from the years 36-39 chambered in 300 savagre, they didn't produce them until 1940.
