The other gun is also a Sedgley Krag but it is not marked and is 30-40. I think it was built after Sedgley quit advertising their Krags and has different sights than what they put on the early sporters that were listed in the catalogs. The 25-35 is one of those that were in the catalogs.
The fourth photo shows a bunch of Sedgley checkered bolt knobs, the left one is the Krag, next a 40s Deluxe, then a 30s Deluxe Engraved, then a 30s Deluxe and the right one is a short action Sedgley. I believe the Krag bolt was checkered later as the catalog doesn't indicate the bolts were checkered. The Krag bolt checkering sure looks like G&H , at least their style.
The fifth photo shows the loading gate which is checkered on both sides, again not what Sedgley would have done. The photo also shows how they shortened the magazine box for the shorter cartridge.
