The gun the turkey huntress is holding is like the two 12 gauge Western Fields I have owned. I'm still not clear as to the correct designation of this model. Typing in Champion, on Google, got me pictures that were not like this. I believe the "Special Trap" model has a ventilated rib. Mine do not, the rib is solid. Choke is swaged, choice of ejection or extraction is made by position of a screw in the barrel lug. Had some success and a LOT of fun, shooting BP cartridges in mine, at BP cartridge trap matches. Sold the first one to a shooting buddy and guess what? He beat me with it!
