0.25mm, in round numbers is .010", which strikes me, considering where that .010 is, as quite close.
Sort of interesting to note the precision that people are capable of. Compare the close clearance between the telescope housing and mirror frame, seems no necessity for such closeness here, though who knows, and the "sloppiness" one encounters in the AK-47, which like the U.S. 45 Caliber pistol "rattled when shook", but which worked. My understanding of these Soviet sextants was that they too "worked"
