Thanks, Dave. No need to remove the stop screw - I was just trying to figure out whether a problem in the 1977 Bowditch of a back sight with a sextant altitude of 141º04.9' was realistic or just some arbitrary example.

Stan,

Yes a Mark II will read up to 145 degrees. Actually perhaps a little further. The index arm outer end is carried in a slot along the arc. If one removed the stop screw you could pick up a couple more degrees if you had to.
