Leitz stereo microsope parts?

[Robin Leech]

Anyone out here know where I can purchase the following used parts for a Leitz stereo microscope?

Leitz stereo microscope, Model TS Widefield.
Made by Leitz Wetzlar ca 1969-1972 or so.

Am interested in particular in the following:
Eyepieces:
6.3X and 16X

Objectives:
1.6X and 6.3X

I have checked everywhere through microscope companies - all to no avail.

Leads, offers for sale, anything appreciated.
