Just got a Davis Mark 15 plastic sextant. Did a few sun sights and found the LOPs to be acceptable. Not as good at the Astra III-B but fair.
The index mirror is a 2nd surface mirror.
The nice thing about the Mark 15 is that it's small and you can carry it easily in the plastic case it comes with and you'll learn how to quickly adjust the sextant for IE, side error etc. It's not solid in holding its adjustment.
Will post more results as time goes by.
