Looking for Olympus IX2 10x and 20x UPLANFLN Phase and Ph1 annulus

I am building an Olympus IX81 for our cell culture, what is missing are 10x UPLANFLN, Ph1 and 20x UPLANFLN, Ph1 objectives for Phase contrast and the Ph1 condenser annulus for the LWUCD condenser. I am looking for a set of these in at least excellent condition (perfect optics, at most minor wear on the exterior).

In return I have to offer either a UApo/340 40x/1.35 Oil Iris objective OR a UPlanSApo 30x/1.05 Silicon Oil objective, both of which are not useful for our purpose. They are both in perfect condition both regarding the optics as well as the exterior.

We are located in Basel, Switzerland.
