The Zeiss Ikon ZI has 28, 35, 50, and 85 framelines built in. Not sure about viewfinder magnification, but you can find it online.
Leicas new and used come with a variety of framelines and viewfinder magnifications, some as wide as 28mm IIRC. Bessa R4A/M is the champ of built-in wide frames.
A little internet searching will get you all the options.
