Yes, they made a whole range of lenses in both M42 and Rollei QBM. Not particularly common nor very rare. The Xenon 1.8/50 pops up on ebay fairly often.
In M42 I had the Curtagon electric 35 f2.8, but at least the barrel is different from the QBM sibling. It was pretty good but I was loaded of 35mm lenses, so I let it go.
I still have the 135 f3.5 tele xenar electric and the barrel is different too, zebra styled. This one has a special rendering. For me it's a keeper.
I also have the Edixa Xenon 50 1.9 and QBM Xenon 50 f1.8. Both excelent.
There are also 28mm curtagons in M42. I don't know about Super Angulons in M42 mount.
