Consider a 90 mm f/6.8 Angulon (not Super Angulon). I have one, and it's a really nice performer and very compact. Although it won't permit much movement, neither will the bellows on my cameras. It was a gift, but I would easily buy it. If you want a somewhat longer wide angle, there is also a 120 mm Angulon. But that's pretty close to your 135mm focal length and you might want to have a bigger spread between the lenses.
As you'll see from above I us e a 90mm f6.8 Angulon, mine's excellent however some early ones I mean the post WWII version can be poor, Frank Petronius who no longer posts here claimed tha any with SN 5 million and higher are fine, I used to have an early one and also borrowed one another both were poor. So best to check earlier ones.
I also have pre WWII version these have a touch more coverage but it's uncounted, it's the barrel that vignettes on the later version before the lens itself runs out of coverage. I use mine for landscape work where the most I use is front tilt and as long as you centre the imeage/lens there,s no problems.
