Mühlbauer MTV 3-B-C/200-1 for experimental use

Mühlbauer MTV 3-B-C/200-1 only 250 h in use last overhaul 2006 not possible to service in factory good condition, running very fine, no vibration. I have certified Z50LS, so it has to be changed to new propeller. So good choise to have backup for experimantal use, for example. At the moment aviable at Wuppertal.

AEIO 540 L1B5D

Looking for overhauled one or used one may be out of time-limit but in good condition.
