If the drain drops toward the inside, the 74 BCD mounting nubs make it super difficult to extricate the chain. I learned this during a test ride of my 1X setup before shortening the chain. I have not found a 74 BCD chain guard. Hopefully, shortening the chain reduces the possibility and frequency of dropping the chain.
Ty for the heads up! It wouldn't look as clean, but perhaps a front derailleur would keep that from happening as well.
As for the chainline....well I actually have decided to put the crank on a different hike, a 1988 Miyata Valley Runner. The chainline works great as a double with a 110mm un55 bottom bracket. But, it has to be said that the 110mm is asymmetrical, the NDS is longer by 3.5mm. The drive side length of the spindle is more equivalent to a symmetrical 107mm un55.
