I have for sale a LOMO apochromatic 70x NA 1.23 water Immersion phase contrast objective with cover slip correction collar (range is 0.10 mm to 0.20mm). Great condition. Tube length is 160 mm.
$107 + actual shipping cost
Collar is slightly stiff but will turn with normal force from fingers. Parfocal length is about 33mm.
I can ship it to established international forum members at cost, but I would not ship it internationally via eBay.
It is listed on my eBay, for more, with photos:
