These scopes fit the same sextant.  Most likely English from the mid-19th Century.  One is a spotting scope without glass, and the other a telescope with glass optics in very good condition.  The tube diameter is 20.4mm and the thread diameter is 23.4 OD with a pitch of ~ .8mm.  The eyepiece filter thread is 19.4mm OD by ~ .5mm pitch.  Send them back in the same condition if they don't fit.
