It is possible that this stands for U.S.(United States) EX(expeditionary) force,which means The forces sent to Cuba in the war of 1898.This is possible depending on the serial number(to date) your shotguns manufacturing year.This could also indicate that your model 1897 shotgun was used by U.S. troops during World war I.Both scenarios are possible.

Serial number "26507" would be a Model 1893 versus a Model 1897. I suspect that you left one-digit out of the serial number. Bert H.
This firearm was manufactured 1906. I am left wondering, though, what the D stands for.

the value of your model 75 Winchester depends on many conditional values such as amount of blueing left wood condition etc. but your model 75 Winchester was made in 1941.
