JOHN E HAND BRASS COMPASS POINTER
Made for one of the military compasses that the John
E. Hand company was famous for. Not sure which one.
5-1/2 inches long. With a bit of elbow grease, these
should polish up quite nice. A rare find if you need one
. Nice collectable if you don't.

EDUCATIONAL DCX 38MM X 50MM
Part of our educational optics series. Double convex,
spherical glass lens, with a focal length of approx.
50mm and diameter of 38mm. Made of glass with pol-
ished face and ground edges. Refractive index is
approx. 1.52. Unused and individually boxed. Perfect
for educational projects, but focal length is not in close
tolerance from lens to lens, so not good for use in a
product you are going to manufacture where the focal length needs to be
exactly the same.
