Estimate of monocular value

Group:

I have two Ernst Leitz Wetzlar monocular microscopes that I would like
to sell but don't have an idea of value.

Both are in original leather covered wood box with objective cases.

No 391151 has 100 oil, 6L/.65, 3/.25. Condenser with iris and
vertical adjustment positioning and filter holder with blue filter.
10X and 6X eyepieces. concave mirror OK, flat mirror cracked. Oil
tube in box and still viscous. Oil use document is dated April 1938.
Frame paint is chipped in places and there are signs of some oxidation
and corrosion but all mechanical items work. Optics appear OK.
eyepieces need cleaning as do most of the stand.

No 291009 looks identical but has lots of brass parts--focusing rack
and knobs. Same condenser setup. 100/1.3 oil, 10X, 45X 6L, 10X and
6X eyepieces. This system looks almost like slightly used new. Not
chipping seen. Just some dust. One objective tube is labeled 1/12 (1
over 12) but can't be opened with hand force.

Any ideas about these units?
