Is there a knowledgable expert out there that can help a new beginner
in replacing the missing objectives on a Reichert Microstar IV. I have
been having loads of trouble sourcing the objectives that I want and
was hoping that there is an equivilant to the Reichert made by either
Leica or the American objectives that will work as well as the
Reichert.

Apparently Reichert, Leica and American Objectives are or were all at
one time part of the same company.
If anyone knows that there are some of the objectives are
interchangable what woud be the make and catalog number for most
importantly the #1730 2.5X Plan Achromatic, #1731 4x/.10 Plan
Achromatic, and #1732 10X/.02 Plan Achromatic, and for a later date
(when i can afford it) #1733 20x/.50 Plan Achromatic, #1734 40x/.66
Plan Achromatic and #1736 100X oil Plan Achromatic?

The manual states the objectives for the microstar IV listed below are
as follows with # denoting the catalog number...

#1727 10X Plan Flour.
#1728 40X Plan Flour.
#1730 2.5X Plan Achromatic,
#1731 4x/.10 Plan Achromatic
#1732 10X/.02 Plan Achromatic
#1733 20x/.50 Plan Achromatic
#1734 40x/.66 Plan Achromatic
#1736 100X oil Plan Achromatic
#1742 10x/.25 Phase Plan Phase Achromatic
#1743 20X Plan Phase Achromatic
#1743 20X Plan Phase Achromatic
#1744 40x/.66 Phase Plan Achromatic
#1749 100x/1.25 oil Phase Neo-Plan Achromatic
#1750 10X Plan Phase Achromatic (ATC2000)New
#1751 40X Plan Phase Achromatic (ATC2000) New
#1752 20X Plan Phase Achromatic (ATC2000) New
#1753 100X Oil Plan Phase Achromatic (ATC2000)
#1754 10X Neo Plan
#1757 40X/.66 Neo-Plan Achromatic
#1758 50X/.80 (oil) Neo-Plan Achromatic

Many thanks for any help

Two more points: I think AO stands for American Optical (Company),
not American Objectives--this may help in your web searches. At some
points in time, the Spencer Lens Co. and AO merged to form AO Spencer
(long ago); then, AO, Reichert, Leitz, and possibly Cambridge
Instruments, were merged into what is now Leica USA. Also, the AO
Series 10, 110, and 120 were pretty good scopes, infinity corrected,
and their lenses are readily available on eBay and elsewhere. I think
they might work fine on your scope for general use (plan achromats
sell on ebay for $20 - $50 ??).
Good Luck I've had several AO scopes, and think they offer good used
value.
