I have never used the 100x oil immersion lens it is a little stained (blue) presumably from previous uses, I assume it works but never had need for that magnification. I have used all the other lenses.
It has 10x eye pieces with four lenses on the turret 4x, 10x, 40x and 100x as photographed. This one is the later Leica made microscope. Handbook here for letitz version.I believe it to be all all original.
